How it works
Enter the start date and the end date (the order doesn't matter — the result is always the absolute difference between them) and see how many days, weeks, and the total in complete years/months/days separate the two dates.
Common uses
Calculating how many days remain until an event, how long a contract or project lasts, how long a relationship has been going, or how much time has passed since an important date.
Frequently asked questions
Does the order of the dates matter?
No. The calculator always shows the absolute difference, regardless of which date was entered first.
Is the result in weeks exact?
It's an approximation (total days divided by 7) — for an exact count in weeks and remaining days, use the total days shown.
