Business Days Calculator
Count business days between two dates, or find the date after adding a number of business days, excluding weekends.
How business days are counted
Business days exclude Saturdays and Sundays, and optionally exclude Brazil's fixed-date national holidays (like January 1st and December 25th). This is useful for estimating delivery dates, contract deadlines, or payment terms.

Frequently asked questions
Does this include movable holidays like Carnival or Easter?
No, only fixed-date national holidays are included; movable holidays vary year to year and are not calculated here.
Can I use this for other countries?
The weekday exclusion works anywhere, but the holiday list is specific to Brazil — turn off the holiday checkbox to count business days by weekday only.
Can I subtract business days from a date?
Yes, enter a negative number in "Business days to add" to count backward from the start date.
