How does it work?

This calculator adds a number of days, weeks or months to a start date. The start date is today by default, so you instantly get the date you are looking for, together with the weekday and the week number.

Days and weeks are added as they are (one week = 7 days). For months, the day of the month is kept: one month after March 15 is April 15. When the target month is shorter (one month after January 31), the result falls on the last day of that month.

It is handy for a deadline, the end of a notice period, a delivery window, a 90-day goal or a project milestone. To go back in time, enter a negative number.

Once you have the date, the “Create a countdown” button opens the create form with the dates already filled in: you get a public page with a progress bar to share and, if you like, email reminders.
