About Time Duration
Time Duration is the amount of time between two points in time.
- 1 year = 365 days (366 in leap years)
- 1 month = approximately 30.44 days
- 1 week = 7 days
- 1 day = 24 hours
- 1 hour = 60 minutes
- 1 minute = 60 seconds
Business days typically refer to Monday through Friday, excluding weekends and holidays.
Leap years occur every 4 years (except years divisible by 100 but not by 400).
