About this calculator
A countdown calculator shows exactly how long until a future date and time — in days, hours and minutes. It subtracts the current moment from your target date and breaks the remaining gap down, counting to a specific time of day if you set one rather than just to midnight.
For example, setting a target of the next New Year’s Day counts down the days left in the year, with a detailed line showing days, hours and minutes remaining. Add a target time such as 18:30 under advanced options for a precise countdown to an exact moment rather than the start of the day.
Use it to count down to a holiday, a product launch, a wedding, a project deadline or a birthday. If the target has already passed, the calculator instead shows how long ago it was, marked "ago".
Frequently asked questions
Does it count down to a specific time?
Yes. Set the target time under advanced options for a precise days-hours-minutes countdown; otherwise it counts to midnight of the target date.
What if the date has passed?
It shows how long ago the date was, marked with "ago".
How is the time remaining calculated?
The calculator takes the difference between your target date and time and the current moment, then converts it into whole days, then the leftover hours, then the remaining minutes for the detailed breakdown.
What time zone does the countdown use?
It uses your device’s local time for "now", so the countdown reflects the clock where you are. The target time you enter is read in that same local time zone.
How many days until a specific date?
Enter the date and read the "time remaining" result, which gives the whole number of days left. Leave the target time blank to count to midnight of that day.
Does it show hours and minutes as well as days?
Yes. The detailed line breaks the countdown into days, hours and minutes together, which is why setting an exact target time under advanced options gives a more precise result than counting only to midnight.
