Frequently Asked Questions

How accurate is the age calculator?

Very accurate — it accounts for leap years and calculates the exact number of days, then converts to years, months, and days. The hours, weeks, and total days are all derived from the exact day count.

How are working days calculated?

Working days exclude Saturdays and Sundays. Public holidays are not automatically excluded as they vary by country and region. Use the date difference tool with "Working Days" filter for business-day calculations.

Can I calculate how many days until a future date?

Yes — use the Date Difference tab and enter today's date as start and your target date as end. Or use the Countdown tab for a live real-time timer that updates every second.

What is the earliest date supported?

The calculator supports dates from January 1, 1900 to December 31, 2100 — covering all practical date calculation needs including historical date research.
