How many days since a date
Enter a date in the past. The tool compares it with today's date on your device and shows the days since, the weeks and days, the total hours, and the period as years, months and days.
Milestones
The milestone table shows the date of each round number of days after your date, such as 100 days, 365 days, 1,000 days and 10,000 days, and whether it is still to come or already passed. Below it you can see the next anniversaries.
Anniversaries and leap days
An anniversary falls on the same month and day each year. If your date is 29 February, the anniversary in a year without a leap day is shown as 28 February. Some people prefer 1 March, so check which one your organisation uses.
What people count
- The days since a wedding, a birth, a move or a first meeting.
- A streak, a habit or a training plan.
- Days since the last incident on a safety sign.
- The age of an account, a company or a project.
Dates in the future
If the date has not happened yet, the tool points you to days until, which counts down to it.
