  • Variable month lengths (28-31 days)
  • Daylight saving adjustments

Time Calculations

1 second = 1,000 milliseconds
1 minute = 60 seconds
1 hour = 3,600 seconds
1 day = 86,400 seconds

Our algorithm accounts for all these variables to deliver 100% accurate results.

Frequently Asked Questions

❓ How accurate is this calculator?

It's millisecond-precise, accounting for leap years, time zones, and all calendar quirks.

❓ Can I calculate age at a past/future date?

Currently calculates from birth to current moment only. Future dates are blocked to prevent errors.

❓ Why do total months use decimal points?

Because months vary in length (28-31 days), we use average month length (30.44 days) for most accurate totals.

❓ Is my birth date stored anywhere?

No! All calculations happen in your browser - we never see or store your data.

❓ How is this different from regular age calculators?

Most tools only show years/months. Ours adds:

  • Days/hours/minutes/seconds
  • Total time lived metrics
  • Live-updating counter
