Hi all, Is there a formula please to deduct one year from a date if the month is january february or march. So if date is in format 30/03/2021 i wanted 2021 to show 2020, so just 1 year reduced from the year if the month is jan,feb or march.i didnt need the day or month to be reduced by a year, just the year itself then the day and date stay same. Thank you

Yet another way, that returns a number, no formatting required.:
Excel Formula:
=IF(MONTH(A1)<4,YEAR(A1)-1,YEAR(A1))
