I don't know the easy way. If I were you, I would analyze it like this:

Today is February 16, there are still 12 days at the end of February and 3 1 day in March, so April1* *12+31is 44 days. Seven days a week, 44 divided by 7 gets 6, and the remainder is 2, that is, Tuesday is six weeks and two days later, so 4. 1 is Thursday.
