Formula Used

The Trading Days Calculator USA uses the following formula to calculate the number of trading days:

Trading Days = Total Days - Weekends - Holidays

Where:

  • Total Days = Number of days between the start and end dates (inclusive)
  • Weekends = Number of Saturdays and Sundays in the period
  • Holidays = Number of US market holidays in the period

The calculator uses a predefined list of US market holidays to ensure accurate results.

Worked Examples

Example 1: January 1-5, 2023

For the period January 1-5, 2023:

  • Total Days = 5 (January 1, 2, 3, 4, 5)
  • Weekends = 1 (January 1 is a Sunday)
  • Holidays = 0 (New Year's Day is observed on January 2, 2023)
  • Trading Days = 5 - 1 - 0 = 4

Example 2: December 24-31, 2023

For the period December 24-31, 2023:

  • Total Days = 8 (December 24, 25, 26, 27, 28, 29, 30, 31)
  • Weekends = 2 (December 24 is a Sunday, December 30 is a Saturday)
  • Holidays = 2 (Christmas Day on December 25, New Year's Eve observed on December 31)
  • Trading Days = 8 - 2 - 2 = 4
