You can see the night sky from any specific date and location by entering the date, time and place into a star map or planetarium program. Star positions are calculated from astronomical catalogue data, so the sky over any spot on Earth can be recreated for any moment, past or future.
Quick answer: to see what the sky looked like on a particular date, you need three things: the date, the place and roughly the time. A free planetarium app such as Stellarium will show it on screen. A personalised star map turns that exact sky into a print, from £21.99, made in Manchester.
What did the sky look like on a specific date?
It depends on where you were and what time it was. On any given night, the stars you can see are set by three things:
- The date. As the Earth travels around the Sun, different stars fill the night side of the sky. The winter sky and the summer sky in the UK look quite different.
- The time. The Earth turns once a day, so stars rise in the east and set in the west through the night.
- The place. Someone in Manchester and someone in Sydney see different skies at the same moment. The further north you are, the more of the northern sky stays up all night.
Put those three together and there is one exact answer for any moment, which is why a star map of a date can be so personal.
How can you see the night sky on a specific date for free?
Use a planetarium app. Stellarium is free on computers and phones. Set the location, then change the date and time, and it redraws the sky as it was. It is also a good way to check any star map you buy: the pattern of bright stars should match.
Our own star map builder does the same thing in its live preview. Enter the date and place, and you see the finished print before you decide to order.
How accurate is a star map of a specific date?
Very, for the stars. Their positions come from star catalogues measured by astronomers, and the Earth's movement is known precisely, so the calculation for a given date, time and place is exact. Our maps are drawn from that data, not from a template. You can read more in the science behind our star maps and are star maps accurate?
What a map cannot show is the weather. If it was cloudy that night, the stars were still there, just hidden.
Do you need the exact time?
No, but it helps. The date and place decide which stars are in the sky that night; the time decides which of them sit overhead. If you do not know the time, pick the hour that makes sense: late evening for a night out, the time on a birth certificate for a birth.
Maps of the same time of year in different years can look alike, because the stars barely shift from one year to the next. Our post on why star maps look similar explains why, and what makes each one different.
Can you see the sky for a future date?
Yes. The sky is as predictable forwards as backwards, so you can make a map for a wedding next summer or a due date before it arrives.
Which dates do people choose most?
- The night you met, see the stars on the night we met
- A wedding or anniversary
- A birth, with the time from the birth certificate
- A move into a first home
- A graduation, proposal or big trip
How do you turn it into a print?
Enter the date, time and place in the star map builder, choose a design and size, and add a line of text. Prints are made to order in Manchester on 285gsm museum-grade art cardstock. Most weekday orders placed before 3:30pm leave the same day, on free tracked UK delivery that usually takes 1 to 2 working days.
Frequently Asked Questions
How can I see what the night sky looked like on a specific date?
Enter the date, time and location into a planetarium app such as Stellarium, or into a star map builder. Both calculate the sky over that spot at that moment.
Can I get a picture of the night sky from the day I was born?
Yes. Use the date, the town and the time on the birth certificate, and a star map shows the sky as it was over that place at that moment.
Does the location change the star map?
Yes. The same moment gives a different sky in different places, especially between the northern and southern hemispheres.
Can I make a star map for a date in the future?
Yes. Star positions can be calculated ahead, so a map can be made for a wedding or due date before it happens.
