Days Until Date
Calculate exact days, business days, and time intervals between calendar dates.
Parameters
Understanding calendar day counting
Days until date calculations compute differences based on the Gregorian calendar cycles. When counting durations, inclusive calculation parameters add 1 day to represent total elapsed day-units.
Business day filters bypass weekend intervals (Saturdays and Sundays) alongside standard US federal holidays. The integrated offset tool handles multi-unit addition/subtraction, respecting month overflows and leap years.
