What Counts as a Business Day

A business day is any weekday when standard commercial operations are conducted. In most countries, this includes:

• Monday through Friday

• Excludes weekends (Saturday and Sunday)

• Excludes official public holidays

• May exclude company-specific closure days

This definition is the foundation for calculating business days accurately.

Total Days in a Year

A calendar year consists of:

• 365 days in a standard year

From this total, we subtract weekends and public holidays to determine the number of business days.

How Many Weekdays Are in a Year

There are 52 weeks in a year, plus 1 additional day (or 2 in a leap year).

• 52 weeks × 5 weekdays = 260 weekdays

• Standard year: 260 or 261 weekdays

• Leap year: 261 or 262 weekdays

The exact count depends on how the year begins and ends.

Business Days in a Leap Year
