Count dates on your working weekdays, remove actual closures, and decide whether both endpoints belong in the range before multiplying by daily hours.
Start with a defined interval
A planning period needs two boundaries and an inclusion rule. Intious includes both dates: Monday through Friday contains five potential working dates, not four. A Monday-to-Monday range contains two Mondays. When someone asks for days remaining after today, start tomorrow; otherwise today can enter the total. Write the chosen rule next to your result so another person can reproduce it.
Separate weekends from closures
A weekend is whichever recurring weekdays your team does not work. A closure is a particular date that would otherwise be worked. This distinction prevents double subtraction. If Sunday is already nonworking, listing the same Sunday as a holiday cannot remove another day. For a distributed team, calculate each location’s actual working calendar before combining capacity; a single national holiday list can miss local closures.
Work through a checkable example
September 7–18, 2026 includes two Monday–Friday blocks: ten potential workdays. If September 7 is a closure, the count becomes nine. At eight paid hours per day, that is 72 planned hours. At 7.5 hours, it is 67.5. Those figures describe a schedule assumption, not time actually worked, billable output or guaranteed employee availability.
Handle exceptions outside the fixed-day model
For a half-day closure, the date should not be treated as a full eight-hour day or a fully excluded day. Count the ordinary dates, then document the partial-day adjustment separately. If every weekday has different hours, calculate groups with the same daily hours or use shift-level records. Preserve the daily CSV so a reviewer can identify exactly which dates contributed to the count.
Try it with your numbers
Count working dates with custom weekdays and closures, then export a daily breakdown.
