February has *30* days every 400 years. It begins with the standard compliment of 28, plus one for the usual leap year, plus another because the Earth's orbit is 365.24 days long, not 365.25. | [reply] |

- No. You're wrong. It's 28 every year, except the mod 4 ones where it's 29, except the mod 100 ones, where it's 28, except the mod 400 ones, where it's 29. (I'm sure there's a mod 2000 requirement there somewhere, but that issue hasn't come up much ...)
- Try learning to multiply and add.
`(365 * 400) + (24 * 4) = 146096 = 365.24 * 400` There's no extra day every 400th year.
- Try learning to spell. It's a "standard compl
**e**ment", and the fact you can't spell is no compl**i**ment to your teachers.
