Find the Number of Weeks Between Two Dates

Google Sheets is a powerful tool for organizing and analyzing data. One common task that many users may need to perform is calculating the number of weeks between two dates. This number can be useful for tracking project timelines, measuring progress, and more. Fortunately, with a few simple formulas, you can easily find the number of weeks between two dates in Google Sheets.

Step 1: Enter the dates

The first step is to enter the two dates you want to compare into Google Sheets. For example, if you want to compare the dates in cells A1 and A2, you could enter them like this:

Step 2: Calculate the number of days

To find the number of weeks between two dates, you must first calculate the number of days between them. You can do this using the simple subtraction formula `=end_date - start_date`, where “end_date” and “start_date” are the cells containing the dates you want to compare. In the example above, you would enter the following formula in cell C2:

Formula: `=B2-A2`

This formula will calculate the number of days between `Date1` and `Date2`, which is 8.

Step 3: Convert days to weeks

Once you have the number of days between the two dates, you can convert this to the number of weeks by dividing by 7 (since there are seven days in a week). You can use the division formula `=days / 7` to do this. Using the data in the table above, you would enter the following formula in cell C2:

Formula: `=(B2-A2)/7`

This calculation will give you the number of weeks between `Date1` and `Date2`, 1.1429. Since you’re most likely looking for full weeks, remove the decimal value and leave a whole number.

Step 4: Round the result to whole weeks

Finally, round down the result to the whole number rather than a decimal. You can use the INT function `=INT(weeks)` to do this. In the example above, you would use the following formula.

Formula: `=INT((B2-A2)/7)`

Live Example in Sheets

For a mixed output with years, weeks, or months, consider using the TIMEDIF add-on. This add-on creates an accurate result with no code.

Conclusion

In conclusion, calculating the number of weeks between two dates in Google Sheets is a straightforward process you can accomplish using simple formulas. Following the steps outlined above, you can quickly and easily determine how many weeks are between any two dates in your spreadsheet.
