Good morning all, and a happy 2015 to everyone.Looking at my diary this morning, I noticed that 2015 is a bit unusual in having Friday 13 in consecutive months: February and March.
Does anyone know how often this occurs, when was the last time, and when is the next time it will happen?
(And no, I don't place any particular significance in the day!) Cheers, John John Pickard [email protected] --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
