Close calendars, payment terms and staffing plans all depend on working days. Count business days between two dates excluding weekends and holidays, and see the fiscal year, quarter and period for any fiscal year start.
How it works
Count calendar and business days between two dates excluding weekends and holidays, identify the fiscal year, quarter and period for any fiscal year-end, and list working days by fiscal month.
Business days = Calendar days − Weekend days − Weekday holidays (both dates included)
Fiscal period = (Month − Fiscal start month) mod 12 + 1
Fiscal quarter = ⌈Fiscal period ÷ 3⌉
Fiscal year = calendar year in which the fiscal year ends (or starts, if selected)Common uses
- Month-end close calendars and reporting deadlines
- Payment terms, SLAs and contract deadlines
- Fiscal-period mapping for budgets and reports

| Start date | 2026-07-01 |
| End date | 2027-06-30 |
| Fiscal year starts in | July |
| Fiscal year named by | Calendar year in which it ends |
| Holidays | U.S. federal holidays (observed) |
| Business days | 250 |
| Calendar days | 365 |
| Weekend days | 104 |
| Weekday holidays | 11 |
| Start date is in | FY2027 Q1 P01 |
| End date is in | FY2027 Q4 P12 |
U.S. federal holidays follow the observed-date rule: a Saturday holiday is observed Friday and a Sunday holiday Monday. Fiscal periods follow calendar months; 4-4-5 and 52/53-week calendars need period-end dates from your own calendar.
Interpreting the results
- Use business days for close calendars, payment terms quoted in business days and staffing plans.
- Fiscal years are most commonly named for the calendar year in which they end; for example, July 2026 to June 2027 is FY2027.
- State, territorial and company holidays differ from the federal list; use a custom list for an exact count.
