About this tool
See how many days are left until any target date, with weeks, months and working-day breakdowns.
Countdown Days Calculator shows exactly how many days are left until any target date, then expands the same wait into weeks and leftover days, a calendar years-months-days breakdown, and the number of working days remaining. An optional target time drives a live ticker that counts down in days, hours, minutes and seconds. Point it at an exam, a due date, a trip or a launch and it keeps updating while the page is open.

Total days, weeks plus leftover days, a years-months-days breakdown and working days remaining, all from one date.
Add a target time and the ticker counts down in real time using your device's local time zone.
Pick a date in the past and the tool reports how long ago it was instead of showing a negative number.
No. Days remaining is the number of whole calendar days from today to the target, so a target of tomorrow shows 1 and a target of today shows 0.
Every day after today up to and including the target date is checked, and Saturdays and Sundays are skipped. Public holidays are not included, so subtract those separately if they matter.
Your device's local time zone. If the event is in another zone, convert the target time to your local time before entering it.
Calendar months vary between 28 and 31 days, so a two-month gap is not a fixed number of days. The total-days figure is the exact one; the months breakdown is how people usually describe the same period.
