So much of it has been lost too. We could do better, though. Teaching what we can would at least teach the general skill of learning languages.

Do we really even need months? They don't even line up with the lunar cycle like they pretend to do.

Just give us Year/Day. On leap years we get an extra long New Year holiday.
