Third grade children's arithmetic problem: today is August 1, Wednesday, ask September 10, October 1, day of the week

Third grade children's arithmetic problem: today is August 1, Wednesday, ask September 10, October 1, day of the week

Because it's Wednesday, August 1st
So next Monday: 8-3 = 5, 5 + 1 = 6
So Monday, August 6th
An August is a big month. So there are 31 days,
So 31-6 + 10 = 35
There are seven days in a week. So, 35 / 7 = 5 (divisible)
So Monday, September 10th
I think September is a small month. So there are 30 days
So 30-10 + 1 = 21
There are seven days in a week. So 21 / 7 = 3 (divisible)
So Monday, October 1st

There are five weekends in April of a certain year. April 1 of this year is a week______ ．

There are 30 days in April, 30 △ 7 = 4 weeks There are at least four days in two days, Saturday and Sunday, and the remaining two days can only be the first two days of April to meet the five weekends. So the first day of April is Saturday, the second Sunday, and the last day (April 30) should be Sunday, so April 1 of this year is Saturday

Third grade mathematics January 1, 2006 is Sunday, so this year's "61" children explain the day of the week?

In 2006, there are 31 days in January, 28 days in February, 31 days in March, 30 days in April and 31 days in May, a total of 151 days. There are 151 days in June 1 children's day, 151 △ 7 = 21 more than 4, so June 1 children's Day is Thursday

What day is it on Wednesday, March 12, 2003 and January 1, 2004

How to calculate the day of the week for a certain day? & nbsp; - Zeller's formula the day of the week for a certain day in history? The day of the week for a certain day in the future? There are many calculation formulas (two general calculation formulas and some sectional calculation formulas) on this issue, among which the most famous one is Zeller's formula

Today is Tuesday. What day is it in 100 days?

100 △ 7 = 14 (weeks) 2 (days); the remainder is 2. Two more days from Tuesday is Thursday. A: two more days is Thursday

Today is Wednesday. What day is it in 30 days? What day is it in 50 days

30/7=4······2,50/7=7······1
So another 30 days is Friday, another 50 days is Thursday

Today is Thursday. From today on, the 150th day is Sunday______ ．

150 △ 7 = 21 (week) A: the 150th day is Saturday

If today is Thursday, what day will it be in 25 days?

25/7=3…… four

Today is Thursday. What day is it in 50 days?

Every seven days a week, 50 divided by 7 equals 7 more than 1, so it's Friday

Today is Thursday, counting from today to the 20th day
Please make a formula

20/7=2.6
The sixth day from Friday is Wednesday
