How this is calculated
Uses the next occurrence on or after today. If the date is today, remaining counts are zero.
The start date is excluded and the end date is included. Dates use Eastern Time (America/New_York).
February 29 occurs only in leap years. Non-leap years are skipped, not changed to February 28 or March 1.
Calendar months are whole months added directly to the start date with end-of-month clamping, followed by remaining days. Months are never calculated as days divided by 30.
U.S. business days exclude Saturdays, Sundays and observed federal holidays. Calendar days equal business days plus weekend days plus excluded observed holiday dates. Actual and observed dates are listed separately; state and employer closures are not included.
