Timestamps, date maths, countdowns, time zones, stopwatch and timer.
Work out dates and times without counting on your fingers: see how many days are left until an event, add or subtract days from a date, count business days, convert time zones, or run a stopwatch and timer. These date calculators open ready to use — enter your dates and read the answer straight away.
The Days Until Date Calculator counts down to birthdays, launches and holidays, the Countdown Calculator ticks live to a moment you set, the Add or Subtract Days Calculator moves a deadline forward or back, and the Stopwatch times anything on screen. Event planners, project managers and students counting to exams are regulars. Two close relatives live with the wider online calculators: the age calculator for exact ages, and the days between dates calculator for the gap between any two dates.
