Time Unit Conversions
Standard Conversions:
• 1 day = 24 hours = 1,440 minutes = 86,400 seconds
• 1 week = 7 days
• 1 month ≈ 30.44 days (average)
• 1 year = 365.25 days (leap year average)
Important Considerations
• Leap Years: February 29th occurs every 4 years, adding one extra day
• Month Variations: Different months have different numbers of days (28, 30, or 31)
• Time Zones: Calculations are based on the dates selected, not specific times
• Holidays: Business day calculations exclude weekends but may need custom holiday calendars
