I don’t think the question in and of itself is silly, and I find some of the comments here patronizing toward T4NK3R.
I think this particular discussion may seem silly because I feel like the emphasis is not where it should be. We should not be looking for a word that in English means «day-and-night,» «a 24-hour-period,» or «calendar day,» but, if anything, a word that means «daytime only.»
That’s because the default meaning of «day» in English is the former.
A week has seven days. (© Loob)
I spent five days working on that project.
I visit her every day.
One day I would like to climb Mount Everest.
Let’s spend the day together.
Let’s move the party to another day.
In none of the above sentences is there an implication of «daytime as opposed to nighttime.» A week consists of seven 24-hour periods, I worked on the project throughout a period of 120 (24 x 5) hours, I visit her once every calendar day (it could be in the daytime or in the evening or at night…), I would like to climb Mount Everest on some calendar day (ditto), the invitation to «spend the day» together doesn’t mean we have to stop when it gets dark, and the party could take place in the evening.
Similarly, when we ask «What time of day?», we are not excluding nighttime.
So this really only becomes an issue if we specifically have to refer to daytime, and although there may not be a single convenient way to do this in every context, we have ways of expressing the idea.
1.) Would you like to meet during the day?
(At least in American English, «during the day» means «in the daytime,» just like «during the week» means «not on the weekend.» I’m not sure if «during the day» is used this way in other varieties of English.)
2.) I don’t like to work out in the daytime.
3.) I spent all morning and afternoon working on the project.
4.) «Day» itself takes on this meaning when used in conjunction with «night»:
six days and five nights
I think of you day and night
As far as the context given here, it’s no exception. If «day» is used, it will be understood in its default meaning unless the context justifies the other interpretation (i.e. if «night» is used as well, as in «12 days and 11 nights»). If he went up to the mountain one time every day for twelve consecutive days and was there in the daytime only, and for some reason it was necessary to emphasize that he was there in the daytime only, then one could potentially say (depending on the context),
He made twelve daytime trips in a row up to the mountain.
For twelve days, he would go to the mountain during the day and return to his hotel in the evening.
So I’m customizing a WordPress (cms) for hotel for a client and he asked me to do add a new functionality that is a options dropdown where the user can select «time» like
Time:
— Day
— Night
I don’t think time is the correct word. What word is there to describe that «time» label? What’s the word for day/night?

The word day has meant one full rotation of the Earth since at least Old English according to the OED.

Yes, and it’s the case with many languages where the word for daytime also is same for an entire day/night cycle.

In Russian, сутки (sutki) refers to an entire day/night cycle. It’s a commonly used word, used in many instances where “day” would be used in English.

In Polish sutki means nipples

Wow. I speak Russian moderately and I didn’t know that. Kind of like the words for minute and blowjob then. Should remember not to mix up сутки in the future.
level 2
true in a scientific context, but most fluent English speakers in a conversational context would just say «day» or «1 whole day», maybe specifying 24 hours.
level 1
Finnish has «vuorokausi», which is the 24h period of a day and a night. Very commonly used and wholly separate from «päivä» = day.
level 2
As for a theory on the etymology:
«Vuoro» means «work shift» and «kausi» means «period». Vuorokausi is a period of work. For example in villages mills could have been rented by a family for a day, so work was done from sunrise to sunrise to take everything out of the shift. Work was done for a «vuorokausi».
level 2
It probably makes more sense to have a distinction there as there are times when there are full days and no day time if your above a certain point
level 1
Danish has the word «døgn».
level 1
In Dutch we have the word ‘etmaal’. It has 2 meanings: a full day or a 24 hr period.
level 2
a full day or a 24 hr period
What would be the difference between the two?
In English, I believe the only related word to etmaal is meal, which was once a more general term that could mean any event that happened at a set time of day.
level 2
In Dutch we use ‘dag’ as both a 24h period and the opposite of night. If we want to be more specific we have the word ‘overdag’ to mean the period that the sun is up.
level 1
I always thought day encompassed the whole day and morning was for dayLIGHT hours. I always argued with my coworkers who would make fun of me for saying “have a good day” after sunset. The day’s still not over, even though dayLIGHT is. Mindf*ck.

Are we missing a good synonym for day and night?
What are day and night?
Daytime is when you can see the sun from where you are, and its light and heat can reach you. Nighttime is when the sun is on the other side of the Earth from you, and its light and heat don’t get to you.
We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it.
It takes 24 hours for the world to turn all the way around, and we call this a day. Over a year, the length of the daytime in the part of the Earth where you live changes. Days are longer in the summer and shorter in the winter.
Top 10 facts
- It takes 24 hours for the Earth to turn all the way around (rotation). That makes one day and one night.
- At any moment, half of the world is in daytime and half is in nighttime.
- The world is like a ball. We call the top half the Northern hemisphere and the bottom half the Southern hemisphere. The (imaginary) line between them is called the equator.
- In the Northern hemisphere, we have summer in June, July and August and winter is in December, January and February.
- In summer the days are longer than they are in winter. In London, the longest day is about 16 hours and 39 minutes and the shortest is 7 hours and 45 minutes.
- In the Southern hemisphere the seasons are the other way around. When it is summer in Europe, it is winter in Australia. Imagine celebrating Christmas on a long, hot summer day!
- To help us understand where we are in the world, we also split the world into right and left halves called the Eastern hemisphere and the Western hemisphere.
- The (imaginary) line between the Eastern and Western hemispheres is called the ‘Prime Meridian’ and it goes through Greenwich Royal Observatory in London.
- The world is split into time zones. Continental Europe is in the time zone to the east of Britain, so time is one hour ahead there; when it is 1pm in Britain it is 2pm in France.
- On the opposite side of the world from London is the International Date Line. On one side of the line time is 12 hours behind Britain, and on the other side time is 12 hours ahead of Britain. That means that it is a different day on each side of the line.

Did you know?
- The Earth is always spinning around – sometimes from where you stand on the Earth you can see the Sun (this is the daytime) and sometimes the part of the Earth where you are is facing away from the Sun so it is dark (this is the nighttime). It takes 24 hours for the Earth to spin all the way around, and we call this a day. Find out more about the sun and the Earth.
- The sun rises from behind the Earth in the East and sinks below the Earth in the West. The time when it appears is called sunrise, and the time when it disappears is called sunset. The length of time between sunrise and sunset is called daytime.
- The Earth spins around an imaginary line that runs between the South Pole and the North Pole. This line isn’t completely straight – so, sometimes the North Pole is pointing away from the sun for long periods of time and it is always dark there, and sometimes the North Pole points towards the sun for long periods of time and it is always light there.
- The Earth is also split into Northern and Southern hemispheres, which are divided by an imaginary line called the equator. The North and South poles are as far from the equator as you can get. Britain is in the Northern hemisphere and is slightly closer to the North Pole than it is to the equator.
- In Britain we don’t have any days when it is always light or always dark, but the days are longer during the times of the year when the North Pole is pointing towards the sun and shorter when it is pointing away from the sun.
- When the days are shorter, there is less time for us to get heat from the sun, so the weather is colder. This is why we get winter. When the days are long, there is more time for us to get heat from the sun so we get hot summer days.
- Because the equator is halfway between the North and South poles, the days there are always 12 hours of daytime and 12 hours of nighttime. There is very little difference between the seasons.
- In the Southern hemisphere the seasons are at opposite times to the Northern hemisphere. When it is summer here it is winter there, and when it is winter here it is summer there.
- The shortest day of the year is called the winter solstice and the longest day of the year is called the summer solstice.
- There are two days each year where every place on Earth has 12 hours of daytime and 12 hours of nighttime. These are called the spring and autumn equinoxes.

About
As the Earth moves around the Sun it rotates on its axis, so we have day and night. The side of the Earth facing the Sun is bathed in light and heat (daytime). The side of the Earth facing away from the Sun, out towards space, is darker and colder (nighttime).
It takes just over 365 days for the Earth to travel all the way around the Sun. We call the length of time the Earth’s revolution around the Sun takes a year, but to make life easier, most years have 365 days and every fourth year has 366 days. We call a year with 366 days a leap year. The extra day is February 29th. The years 2012 and 2016 were leap years; 2020 and 2024 will also be leap years.
The further you are from the equator, the longer a day will be in summer and the shorter it will be in winter. On the longest day of the year in London there are about 16 hours and 39 minutes of daylight, but in Edinburgh, 400 miles north of London, there are 17 hours and 36 minutes of daylight. This is because Edinburgh is further away from the equator than London is.
To help us know where we are in the world, we also divide the world into Eastern and Western hemispheres. The line between them is called the Prime Meridian and it runs through the Greenwich Royal Observatory in London. All measurements of how far East and West places are are taken from this line. We call these measurements longitude.
Midday is the time in the Earth’s rotation when the position of the sun is at the same longitude. The sun has travelled half way across the sky and still has half way to travel.
For people living on the far side of the world, when it is midday in London, it will be the middle of the night for them. It is more useful for them to set their clocks by when the sun will be visible where they live than when it will be visible in London.
For this reason we divide the world into ‘time zones’ so that the time on the clock matches the position of the sun in the sky. Most time zones are set as an exact number of hours ahead of or behind the time in London. The time in France is one hour ahead of London and the time in New York in the USA is 5 hours behind London.
Most countries prefer to be in only one time zone. That way all the schools and offices open and close at the same time and nobody gets confused. This means that the boundaries between time zones aren’t always straight so that all of the country is in one time zone, even though part of the country should be in another one. The USA is so big that it is in several time zones.
On the far side of the world from Greenwich is the International Date Line. On the western side of the line the time is 12 hours ahead of London and on the eastern side of the line the time is 12 hours behind London. This means that on the western side of the line it is one day later than on the eastern side of the line.
Sometimes we change the time of the clocks so that we can make more use of the hours of daylight. If we used the same time all year around in Britain then, in the summer, the sun would rise at 3:30am and set at 8:30pm. Not many people are awake at 3:30am, but lots of people are awake after 8:30pm. We set our clocks forward one hour in the spring so that the sun rises at 4:30am and sets at 9:30pm and we set them back one hour in the winter. This is called summer time.

- Latitude – This is a number between 0 and 90 that tells you how far from the equator you are. The latitude of the equator is 0°, and the latitude of the North Pole is 90°.
- Longitude – This is a number between 0 and 180 that tells you how far from the Prime Meridian you are. The longitude of the Prime Meridian is 0°, and the longitude of the International Date Line is 180°.
- Nighttime – the time when a place on Earth is facing away from the Sun’s warmth and heat
- North Pole – the northernmost place on Earth
- Prime Meridian – the line dividing the Eastern and Western hemisphere, running through Greenwich Royal Observatory in London
- Revolution – the movement of the Earth around the Sun.
- Rotation – the movement of the Earth turning on its axis. A complete rotation takes 24 hours.
- Seasons – There are four seasons: spring, summer, autumn and winter.
- Solstice – The longest and shortest days of the year are the Summer Solstice and Winter Solstice.
- South Pole – the southernmost place on Earth

There are 24 hours in a day. The day is divided into day(time) and night(-time). Daytime is from sunrise (this varies, but we can say approximately 6am) to sunset (we can say approximately 6pm). Night-time is from sunset to sunrise.
Every day starts precisely at midnight. AM (ante-meridiem = before noon) starts just after midnight. PM (post-meridiem=after noon) starts just after midday. This means that 12am and 12pm have no meaning.
This diagram shows the cycle of a 24-hour day and the words we use to describe its parts. The day starts at midnight (at the bottom of the diagram).
The word day can have two meanings:
1. the 24 hours between one midnight and the next 2. the time between sunrise and sunset (as distinct from night)
