Overview

A month is not a fixed quantity: its length depends on the calendar. The conversions below use the Gregorian mean month (2629746 seconds), so they are honest only as a statistical average, never as calendar-correct arithmetic. For that, reach for a calendar-anchored type such as month.rb.

ago and hence (via Relative) inherit the same caveat: they displace by the mean month rather than an actual calendar month, so they are approximate, not calendar-correct. Months is slated for removal in 0.5.0.
