Time Calculators
Age, date, and countdown calculators for tracking time.
About Our Time Calculators
Calculate durations, find differences between dates, or figure out your exact age. Our time calculators handle leap years, time zones, and calendar quirks so you get the right answer every time.
Frequently Asked Questions
Do the date calculators account for leap years?
Yes. All date calculations correctly handle leap years, including the century rule (years divisible by 100 are not leap years unless also divisible by 400). February 29 is counted accurately in every calculation.
How is age calculated exactly?
Our age calculator counts completed years, months, and days from your birth date to today. It follows the common convention where you turn a year older on your birthday, not the day before.
Can I calculate the number of working days between two dates?
Our date difference calculator can show the total number of days between two dates. For working days specifically, subtract weekends from the total — we plan to add a dedicated business-day calculator soon.
What time zone do the calculators use?
Date and time calculations use your local device time zone by default. This means results automatically match the clock on your computer or phone.
