Frequently asked questions
How are months and weeks counted when units overlap?
The breakdown counts each unit from the largest down. From 2024-01-15 to 2025-03-10, that's 1 year, 1 month, 24 days — years are counted first, then whole months from the remainder, then days. The totals panel shows each unit as a standalone value (e.g. 14 months total).
Does the calculator account for leap years?
Yes. Because we use Luxon for the calendar math, leap days are included automatically. February 29 days are counted as actual days, and 'one year' from 2024-02-29 lands on 2025-02-28.
What timezone do the dates use?
Both inputs are interpreted in the same zone-agnostic frame, so the duration is unaffected by your local timezone or daylight saving. If you need to compute the gap between two specific instants in different zones, convert them with the Timezone Converter first.
Can the duration be negative?
Yes. If the 'To' date is earlier than the 'From' date, the breakdown is still shown but tagged as negative. The totals panel always uses the absolute magnitude.
