datime brings together the time tools people use every day: a timer you can chain for intervals, a lap stopwatch that exports to CSV, an alarm clock with multiple alarms, countdowns to 31 key dates and the exact time in 1022 cities.

Every date is recalculated automatically each day: Easter with the computus algorithm, movable holidays, long weekends and DST changes. Nothing is hard-coded, so nothing goes stale.
