In my time and my society, time is divided up into years, months and days. There are twelve months in one year but the 365 days that make up one year can't be divided evenly by 12 so each month has a different number of days.
I remember how many days each month has because I saw a pattern in the values, and apply a rule to know. Let me explain.
If I want to know how many days there are in a month I ask myself 3 questions very quickly. Firstly I ask is the month February because that is the only month with 28 days. Then I ask if the month's numeric value is an odd or even number. March is the 3rd month so it is an odd number. Then I ask myself if it is before august because all odd months before august have 31 days, all odd months after august have 30 days, all even months from August have 31 days and all even months before August have 30 days except for February with 28 days.
