Today is the Ides of March. Should you be wary? Not unless you have a fear of the number 15...or some soothsayers warned you in particular.

Now if you want to be wary-be wary of the Kaland of April. Indeed be wary of the Kalend of each month. The Kalend is the 1st of the month...when bills are due!
