Determining a date's quarter
For financial reports, you might find it useful to present information in terms of quarters. The following formula
returns an integer between 1 and 4 that corresponds to the calendar quarter for the date in cell A1:
=ROUNDUP(MONTH(A1)/3,0)
This formula divides the month number by 3 and then rounds up the result.
Converting a year to roman numerals
Fans of old movies will like this one. The following formula converts the year 1945 to Roman numerals:
MCMXLV:
=ROMAN(1945)
This function returns a text string, so you can't perform any calculations using the result.
Finally! The long-awaited companion function was introduced In Excel 2013. Use the
ARABIC function to convert a Roman numeral to a value. Here's an example, which re-
turns 1945:
=ARABIC(“MCMXLV”)
