Has this year had the most Friday the 13ths in recent memory? According to Wikipedia, yes, although it’s not as rare as I would have assumed.
What is relatively rare, however, is that this year’s Friday the 13ths have fallen thirteen weeks apart!
And is this the reason why DAs of late seem much harder than I can remember? Is Friday the 13th influencing DA?
Update:
Pretty easy (for DA!) this week. All out with no help in under an hour.
I liked the defs in 11A and 24D.
25A brought back memories, as did 4D.
