How Time Conversion Works

All time conversions on this page are built on a small set of exact base values:

  • 1 minute = 60 seconds
  • 1 hour = 60 minutes
  • 1 day = 24 hours
  • 1 week = 7 days
  • 1 month = 30 days (standard planning convention)
  • 1 year = 365 days

To convert from one unit to another, we move through minutes: convert the source unit to minutes, then from minutes to the target unit. This keeps every conversion consistent and easy to verify.
