FAQ

Do you account for time zones?

We normalize all calculations to UTC to avoid offsets between devices. Enter dates only; no need for times unless you export elsewhere.

Can I include weekends in business counts?

Yes. Toggle the weekend checkbox to include or exclude Saturdays and Sundays from the working-day total.

How accurate are month or year estimates?

Months use the average length of 30.4375 days and years use 365.25 to cover leap cycles. For exact statements, rely on the ISO date output.
