How many weeks between dates mail merge

A mail merge question!

To calculate the number of weeks between two dates using a mail merge, you can use a combination of the DATEPART function and some simple arithmetic.

Assuming you have two dates in your data source, let's say Start Date and End Date, you can use the following formula:

=INT((End Date - Start Date)/7)

This formula calculates the difference between the two dates in days, then divides that result by 7 to get the number of weeks.

Here's a breakdown of the formula:

For example, if Start Date is 2023-03-01 and End Date is 2023-04-15, the formula would calculate:

=INT((2023-04-15 - 2023-03-01)/7) = INT(14/7) = 2

So, the result would be 2, indicating that there are 2 weeks between the two dates.

In your mail merge, you can use this formula to populate a field with the number of weeks between the two dates. For example:

The project will take approximately {=INT((End Date - Start Date)/7)} weeks to complete.

Note that this formula assumes a standard 7-day week. If you need to account for varying week lengths (e.g., due to daylight saving time), you may need to use a more complex formula or a dedicated date and time library.
