Question

In a certain year, January had exactly four Tuesdays and four Saturdays. On what
day did January fall that year?

Answer 1

As we have 31 days in January, then we have also 3 days of week 5 times and these 3 days are 29th, 30th and 31th of January, so these 3 days should be between Tuesday and Saturday not to have these days repeat 5 times.
So, if in a certain year, January had exactly four Tuesdays and four Saturdays, then January starts that year on Wednesday and ends on Friday.
