You just need to remember that every year you add, that day will add another day. For example, in 2006, 5438+0, 10 is Monday, and in 2002, 10, 1 is Tuesday. And so on. 365 days a year is 365÷7. Since there are seven days in a week, the remainder is 1, so 1+ 1=2, the answer is Tuesday.

Formula: 365÷7=52 (days) ... 1 (days)

1+ 1=2

June, 2002 10 is Tuesday.
