If October of a certain year has 5 Wednesdays, on what days of the week could Halloween fall? Note: Halloween = October 31
For this to occur either the 1st 2nd or 3rd must be a Wednesday
which would make Halloween (the 31 st) be a Friday Thursday or Wednesday respectively
The 1st, 2nd or 3rd of the month could be a Wednesday, giving 5 Wednesdays in the month. If the 1st is a Wednesday, then the 29th would also be a Wednesday. That would make the 31st a Friday. If the 2nd is a Wednesday, so is the 30th, so Hallowe’en would be on Thursday. If the 3rd is a Wednesday, so is the 31st.
