⏳ Instant conversion of time units

Our tool helps you quickly convert seconds to days, hours to minutes, or find out how many seconds there are in a year. This is more convenient than counting in your head or looking for formulas.

Time +⌛ How to add time (hours, minutes, seconds) Our smart calculator does what a regular phone calculator can't do: it adds up time intervals, taking into account that there are 60 minutes in an hour, not 100.
Time -⏱ How to calculate the time between two events Our calculator helps you find out the exact difference between two time points. This is useful when you need to calculate hours worked, travel time, or distance traveled.
Time ⇄⏱️ Instant conversion of time units This tool allows to convert any time periods: from seconds to centuries. You don't need to remember formulas or use a calculator—just enter a known value and the system will fill in the rest of the fields.
  • Programming: converting timestamps and logs (usually in seconds/milliseconds) into understandable dates.
  • Planning:calculation of the total time to complete tasks in hours.
  • Study: solving problems in physics that require conversion to the SI system (seconds).

📐 Cheat sheet: Translation formulas

For those who want to calculate manually, we have collected the basic values:

  • 1 minute = 60 seconds
  • 1 hour = 3600 seconds
  • 1 day = 86,400 seconds
  • 1 year (non-leap year) = 31,536,000 seconds

Frequently asked questions (FAQ)

🔹 Does the calculator take into account leap years?

In standard conversion mode, a year is counted as 365 days. If your task requires astronomical accuracy taking into account leap years (366 days), we recommend calculating the number of days separately.

🔹 Is it possible to enter fractional numbers (for example, 1.5 hours)?

Yes, the calculator understands decimals perfectly. If you enter 1.5 hours, the system will correctly translate this as 90 minutes or 5400 seconds.

🔹 What is the maximum number you can enter?

The tool can handle huge values (up to millions of years). However, when converting very large quantities (billions of years), a slight rounding error in the last decimal places is possible.

🔹 Are my calculations saved?

No, everything happens locally in your browser. We do not see or store your data.
