date_interval
shallowdev.almanack/almanack · Verify this server
The distance between two dates. 'days' is the exact signed count (negative when end precedes start) and is always reliable. 'calendar' breaks the same distance into whole years, then whole months, then days, using the clamp policy, so adding that breakdown back to the start date with add_to_date returns the end date exactly. Exact integer arithmetic; never estimates.
