$$1$$ May is $$6+30+1=37$$ days after March $$25$$. Since $$37\div7=5 \text{ R }2$$, $$5$$ weeks after is still Monday and $$2$$ days after that is a Wednesday. 
Given March $$25$$ of a certain year is Monday, what day of the week would May $$1$$ fall on that year? ． 

Tuesday 
Wednesday 
Thursday 
Friday
