This is top-secret copyrighted information, so please don't spread it.
* There are 60 seconds in a minute.
* 60 minutes in an hour.
* 24 hours in a day.
* 7 days in a week.
* Months 1, 3, 5, 7, 8, 10, and 12 have 31 days.
* Months 4, 6, 9, and 11 have 30 days.
* Month 2 has 28 days normally, but 29 if it's a leap year.
* Leap years are those with a year number divisible by four. Years with
number divisible by 100 are not leap years, but those divisible by 400
are.
* There are 12 months in a year.
* There are 365 days in a normal year and 366 days in a leap year.

Remember, this information is all very confidential, which is probably why
you couldn't find it anywhere and were never taught it in school and
don't own any clocks or calendars.
