Weekday breakdown

Monthly breakdown
Regular shifts, extras, removed days, and work time.
Counted shift dates
Shift-week equivalents are a workload-style measure based on selected regular workdays, not necessarily complete calendar weeks. Each date counts at most once.
What this work-shift calculator tells you
Count your remaining shift dates and working time through an end date. Customize regular weekdays, remove days off, add extra shifts, and review the next shift, final shift, and schedule breakdowns.
How regular shifts are counted
The start date is excluded by default and the end date is included. A regular shift occurs when a date is inside that interval, its weekday is selected, and it is not listed as a day off.
How to enter days off and extra shifts
Enter real YYYY-MM-DD dates separated by commas, semicolons, or new lines. Days off remove regular shifts; extras add a shift only when that date is not already an active regular shift. A date cannot appear in both lists.
How remaining work hours are calculated
The calculator multiplies the final shift count by the fixed hours-and-minutes shift length. Breaks and unpaid time are not subtracted, so enter the working duration appropriate for your plan.
Worked example
From July 29 through August 31, 2026, excluding the start and working Monday through Friday, there are 23 regular scheduled shifts. Removing August 14 and adding August 15 leaves 23 total shifts, or 184 hours at 8 hours each. July has 2 shifts and August has 21.
Frequently asked questions
Is the start date counted?
Not by default. Enable the start-date checkbox to count it when it qualifies.
Is the end date counted?
Yes, when it is an active regular shift or a valid extra shift.
Can I include weekends as regular workdays?
Yes. Select Saturday, Sunday, or both in the regular schedule.
How do I remove vacation days or scheduled leave?
Add each affected scheduled work date to the Days off field.
How do I add overtime or an extra weekend shift?
Add its date to Extra shifts. It counts once when it is inside the selected range.
What happens if the same date is entered as both a day off and an extra shift?
The calculator shows a conflict error and asks you to remove the date from one list.
Can one date count as two shifts?
No. This version counts each calendar date at most once, even when an extra date is also a regular workday.
Does the calculator support night shifts?
Yes for counting purposes. Assign an overnight shift to the calendar date on which it starts.
Does the calculator subtract breaks or unpaid time?
No. Total time uses the fixed shift length exactly as entered.
Can I use this for rotating schedules such as four days on and four days off?
Complex repeating rotations are not supported directly. Verify the result or model exceptions manually with extra-shift and day-off dates.
