In the May 1982 Kickshaws, Darryl Francis challenged Word Ways Readers to find Websterian transadditions of the Jewish, Muhammadan, Hindu and French Revolutionary calendar names (all listed in Webster's). I have accepted this challenge, with the results given below. Most of the words can be found in both Webster's Second and Third Editions, but those followed by 2 are only in Webster's Second. An asterisk denotes a pure transposition; no added letters were needed.
