Frequently Asked Questions
How is the years/months/days breakdown calculated?expand_more
We calculate calendar-accurate years, months and remaining days by walking month boundaries, so results correctly account for varying month lengths and leap years.
What counts as a "business day"?expand_more
We count the exact number of weekdays (Monday–Friday) between the two dates. This does not account for public holidays, which vary by country and region.
What happens when I add a month to the 31st?expand_more
If the resulting month is shorter (e.g. adding a month to January 31st), the date is clamped to that month's last day — January 31st + 1 month gives February 28th (or 29th in a leap year), matching how most calendar and spreadsheet tools behave.
Can I calculate a date far in the future or past?expand_more
Yes, both the difference and add/subtract tools support any valid calendar date supported by your browser.
