Hi kt17, I've a feeling this is going to come as quite an anticlimax. I hadn't realised (until Googling) that there has been a recent realignment in some astrological divisions but the clue is based on the "traditional" dates which I believe only vary by days from year to year - as you can tell I'm not a "follower".
When Aries begins : March
and finishes very early : Mar(c)(h)
[my thoughts being early would only remove the "h"]
Aries sign: Ram (and how it relates is a palindrome).
Bet you wish you hadn't asked now.
