1. What is the Calendar Back Date Calculator?

The Calendar Back Date Calculator calculates a date in the past by subtracting a specified number of days from a given current date. This tool is useful for various planning, scheduling, and historical date reference purposes.

The calculator uses the simple date subtraction formula:

Where:

• \( Current Date \) — The starting date from which to subtract days
