About Business Days

What are Business Days?

Business days typically refer to Monday through Friday, excluding weekends (Saturday and Sunday) and public holidays.

How to Calculate

To calculate business days between two dates, count all days excluding weekends and any holidays that fall on weekdays.

Business Use Cases

Business days are used for calculating deadlines, delivery dates, project timelines, and service level agreements.

Examples

Days Between Dates

From June 1 to June 7 (excluding weekends) = 5 business days

Add Business Days

June 1 + 5 business days = June 8 (skipping weekends)

Subtract Business Days

June 10 - 3 business days = June 7 (if June 8-9 are weekends)
