Frequently asked questions
Does this include public holidays?
No — it counts all Monday–Friday days regardless of public holidays. For holiday-aware calculations, use the Business Days calculator with a specific country calendar.
Are the start and end dates included?
Both the start date and end date are included in the count if they fall on a working day.
What defines a "working day"?
This calculator defines working days as Monday through Friday. It does not account for regional weekend variations (e.g., Friday/Saturday in some countries).
Counting working days between dates
Why working days matter
Many business processes — invoice payment terms, delivery SLAs, legal notice periods, employee notice periods — are defined in working days rather than calendar days. Counting them manually across weeks requires checking a calendar; this tool does it instantly.
The difference between working days and business days
Working days simply exclude weekends (Saturday and Sunday). Business days go further by also excluding public holidays specific to a country or region. Use the Business Days Calculator for country-specific holiday exclusions.
