The moon has always accompanied mankind. Many calendars were based on the changes in the phases of the moon. An interesting question is how long is one day, night and whole day on the moon in terms of earth days.
If we were standing on the moon, it would be 29 Earth days (days) before the sun traveled all the way through the sky and returned to its original place. So one moon day lasts about 29 days. If we divide this time into the period of the day when the sun would illuminate us and the night, it turns out that a day on the moon would last about 14 earthly days. The night would have been similar.
