About the Countdown Timer Calculator

A countdown timer breaks the gap between now and a target moment into a full days-hours-minutes-seconds readout, rather than just a single day count.

Formula: Time Remaining = (Target Date + Target Time) − Current Date and Time, converted into days, hours, minutes and seconds.

Enter any future date and time to see exactly how long is left. If the target has already passed, the calculator reports how much time has elapsed instead. Great for tracking countdowns to launches, deadlines, events or trips down to the second.
