Time Units

These are duration conversions, not calendar arithmetic. A month here is the 30.44-day average and a year is the Julian 365.25 days, which is the right convention for elapsed time and the wrong one for "three months from Tuesday". Each page says so, and points at the date tools for the calendar case.
