Hi Epinn,

To convert a month to a quarter using date functions, you can use the following formula:

In this formula, C1 is the cell containing the month (e.g. "Jan", "Feb", etc.). The DATEVALUE function is used to convert the month to a date by concatenating it with "1-" and "-2000" to create a date in the format "1-Jan-2000". The MONTH function then extracts the month number from this date, which is then used in the same formula you provided to calculate the quarter.

Here are the steps to use this formula:

1. Enter the formula in a cell where you want the quarter to be displayed.
2. Replace "C1" in the formula with the cell containing the month.
3. Press Enter to calculate the quarter.

This formula should work for any month entered as text (e.g. "Jan", "Feb", etc.). Let me know if you have any questions or if there's anything else I can help with.

Best regards,
