Time & Date Conversion Facts

Understanding these facts helps you use the tools effectively.

Key Statistics

  • 24 primary time zones worldwide (roughly 15° longitude each)
  • Unix timestamps count seconds since January 1, 1970
  • Daylight saving changes affect offsets
  • Date math accounts for leap years and month lengths
  • Real-time conversion improves accuracy for “now”

Best Practices

Guidelines for accurate results.

Quality Considerations

  • Verify DST status when scheduling
  • Check differences before important calls
  • Consider leap years in date math
  • Use live conversion when it matters
  • Double-check for critical events

When Not to Use

  • Historical dates without verifying DST rules
  • Very far future dates (rules may change)
  • When official/legal time is required—verify with authoritative sources
  • Do not rely on tools alone for legal time obligations
