Lesson Excerpt:
Did you know that calendars have been around for thousands of years? Most ancient calendars were lunar calendars, which means that they were based on the cycle of the moon around the earth. A lunar month is 29 ½ days.
The calendar we use today is called the Gregorian calendar. In the Gregorian calendar some months have 30 days and some 31 days. February has only 28 days. The number of days add up to 365. But a year actually has 365 ¼ days, which means that every 4th year we have an extra day. In our calendar we add this day onto February. We call this year a leap year. All the leap years can be divided by 4 (except for millennium years which are only leap years if they can be divided by 400). Here is a verse to help you remember the number of days in the months:
