About the Time Tool
Time is the one measurement system that stayed stubbornly non-decimal. Sixty seconds to a minute, sixty minutes to an hour, twenty-four hours to a day, and then months of irregular length — an inheritance from Babylonian arithmetic that no reform has managed to displace.
That irregularity is exactly why a converter helps. Working out how many minutes are in six weeks, or how many hours a 90-day project contains, is arithmetic nobody enjoys doing mentally. This converter handles it instantly in your browser.
How to Use Time
- Enter the time value.
- Select the source unit.
- Select the target unit.
- Read the converted result.
When to Use This Tool
- Calculating project durations across different time units
- Converting video or audio lengths from seconds to readable format
- Working out billable hours from minute-based time logs
- Estimating total hours in a multi-week schedule
- Converting timeout or cache values between seconds and hours
Things Worth Knowing
- A year is taken as 365 days for conversion purposes; leap years add a day every four.
- A month has no fixed length — conversions typically use an average of about 30.44 days.
- A week is exactly 7 days and is the only irregular-seeming unit that is actually consistent.

Frequently Asked Questions
How many seconds are in a day?
86,400. That is 60 seconds × 60 minutes × 24 hours, and it appears constantly in caching and session configuration.
Why is a month not a fixed length?
Because months derive from lunar cycles that do not divide evenly into a solar year. Lengths were adjusted repeatedly for calendrical and political reasons, leaving the irregular pattern we have.
How many hours in a work year?
Roughly 2080 for a standard 40-hour week over 52 weeks, before deducting holidays and leave. Actual working hours are typically closer to 1800–1900.
What is a leap second?
An occasional one-second adjustment added to keep atomic clocks aligned with Earth’s slightly irregular rotation. They are announced in advance and are not part of routine conversion.
