Time & Duration Converter

Time is the only measurement system that successfully resisted decimalization. Rooted in ancient Babylonian base-60 mathematics, converting time requires jumping between base-60 (minutes/seconds), base-24 (hours), and base-365 (years), making a calculator indispensable for logistics, astronomy, and computing.

The Math of Time

• Minute: 60 Seconds
• Hour: 60 Minutes (3,600 Seconds)
• Day: 24 Hours (86,400 Seconds)
• Year: 365 Days (31,536,000 Seconds)

What is Unix Epoch Time?

If you are a programmer, you deal with Unix Time. Instead of tracking months and years, computers simply count the total number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This single massive number (currently over 1.7 billion) allows computers to effortlessly calculate time differences without worrying about time zones or leap years.

Frequently Asked Questions

Does this account for Leap Years?
Standard time converters assume a flat 365-day year for generic conversions. If you need precise calendar math that accounts for leap years, use our dedicated "Date Difference" calculator instead.
