Frequently asked questions
Does the order of the two dates matter?
No, enter them in either order, the tool always calculates the absolute difference between the earlier and later date.
Why do the months and years figures round differently than days ÷ 30 or ÷ 365?
Months and years are calculated by counting actual calendar months and years elapsed, not by dividing the day count by an average month/year length. That makes them accurate for real calendar spans that include different month lengths and leap years, rather than an approximation.
Can I use this for counting down to a future date?
Yes, set one date to today and the other to any future date, the day/week/month/year counts work the same whether the second date is in the past or the future.
