Adding 3 months-

Good morning,

Currently I have a sheet with hundreds of entries, and I need to add 3 months to the months in Column A.
In Column A I have January, February etc.. I need to add 3 months in Column B using column A. Example: A1 January, B1 April
A2 June, B2 September. There's no particular order all I want to do is add 3 months to the month that's showing in column A. etc..
Sorry for any confusion.



Any help is helpful!

Thank you,
