Working with Quarters in Excel
You might not know that Excel knows about quarters. That’s 3 months, not 25 cents.
If you type Q1 in a call and drag the cell with the Fill Handle (bottom right corner of cell) you will see that Excel repeats the sequence Q1, Q2, Q3 and Q4. It doesn’t do Q5 or above.
This works for Qtr1 as well.
