Business days calculator

Count working days between two dates — skipping weekends and holidays — or find the date that's a number of business days away.

Free, no sign-up

Before you use it

Works well for

  • Delivery and payment deadlines in business days
  • Counting working days in a period
  • Brazil national holidays and US federal holidays

Not the right tool for

  • State, city or company holidays — subtract them yourself
  • Court deadlines: courts have their own calendars and recesses

What counts as a business day

Monday through Friday, excluding the holidays you select. US federal holidays use their observed dates: when a holiday falls on a Saturday it's observed on Friday, and on a Sunday it's observed on Monday. You can also switch to Brazil's national holidays or ignore holidays entirely.

Add business days

Use the second section for shipping estimates, invoice due dates and "within 10 business days" promises. Both the start and end dates are included in the count of the first section.

Frequently asked questions

Are state holidays included?

No, only federal (or national) holidays. Count state or company holidays manually.

Can I count Saturdays as working days?

Yes, tick "Saturday is a working day".

Does the start date count?

In the date-range count, yes. When adding business days, counting starts the day after the start date.
