What is a Calendar Back Date?

A calendar back date refers to a date in the past relative to a given date. This concept is used to determine how many days have elapsed between two dates or to find a date that is a certain number of days before or after a given date.

Example Calculation 1

Let's assume the following values:

Step 1: Use the formula:

\[ D = |2024-07-15 - 2024-07-01| = 14 \]

The number of days between the two dates is 14 days.

Example Calculation 2

Let's assume the following values:

Step 1: Use the formula:

New Date = 2024-07-15 - 10 days = 2024-07-05

The new date 10 days before the base date is 2024-07-05.
