Direct answer
Count the date range normally, then remove the company shutdown dates from the workday total if they are not scheduled workdays.
The search intent behind "count workdays with company shutdown week" is usually practical: the person has a time card, paycheck, policy, schedule, notice date, or PTO balance in front of them and needs the next number to check.

Open Work Days CalculatorReal workplace situation
A company shutdown week can distort project timelines, benefit deadlines, and PTO planning. Public calendars still show weekdays, but the employer may treat those dates as non-workdays.
For planning, build the normal weekday count first. Then subtract the shutdown days that fall inside the range. This keeps the difference between public weekends and company-specific closures visible.
Date range: December 15-January 9. Normal weekdays: 20. Company shutdown: December 24-January 1 includes 7 weekdays. Adjusted workdays = 13, assuming all shutdown weekdays are non-workdays.
Step-by-step calculation
Key checks
- Enter the start and end date for the full range.
- Count weekdays first.
- List every shutdown date inside the range.
- Remove only shutdown dates that would otherwise be workdays.
- Keep the final count with the shutdown assumption attached.
Working rule and example table
Adjusted workdays = weekdays in range minus company shutdown weekdays and other custom non-work dates.
Use the table as a quick audit trail. It gives you a short way to explain the calculation to payroll, a manager, a client, or yourself later when the pay stub or calendar reminder arrives.

| Item | What to use | What to write down |
|---|---|---|
| Source | Time card, schedule, policy, pay stub, contract, PTO balance, benefit notice, or invoice record | Name the record and date |
| Formula | Adjusted workdays = weekdays in range minus company shutdown weekdays and other custom non-work dates. | Keep hours, rates, dates, and deductions separate |
| Result | Date range: December 15-January 9. Normal weekdays: 20. Company shutdown: December 24-January 1 includes 7 weekdays. Adjusted workdays = 13, assuming all shutdown weekdays are non-workdays. | Copy the result with assumptions attached |
More realistic variations
Paid shutdown: may still count for pay but not for project work capacity.
Partial shutdown: remove only the closed departments or dates that affect your team.
Holiday overlap: do not subtract the same closure twice if a holiday is already excluded.
Policy and edge-case notes
Workday count and paid-day count may be different during a shutdown.
Contract deliverables should follow the contract definition of business days.
If the shutdown is optional PTO, count it based on the actual staffing plan.
Common mistakes that change the answer
Do not count every weekday as a workday when the office is closed.
Do not subtract weekend shutdown dates from a weekday-only count.
Do not use a public holiday calendar when the company closure list is different.
