Time & Date
Work out the time between two dates or times, add or subtract time from a date, or convert a Unix timestamp, all aware of real calendar rules.
Calculate an exact age, the calendar difference or day count between two dates, add or subtract time from a date, work out elapsed shift time with an optional break, add up a list of durations, or convert a Unix timestamp.
Working out how many days remain until a deadline, or the decimal hours worked across a shift.
Conventions and limitations
Date and duration tools each state their own counting convention explicitly (inclusive or exclusive, end-of-month clamping, and so on), since these conventions genuinely differ between tools and it matters which one applies.
