Calculation of the day of the week for 19th September 1944

To determine the day of the week for 19th September 1944, we need to count the number of days between 15th September 1943 and 19th September 1944, and then divide the number of days by 7. The remainder will give us the day of the week.

Counting the number of days

We can use a calendar to count the number of days between 15th September 1943 and 19th September 1944. We can count the number of days in each month and add them up. We also need to consider the leap year.

- From 15th September 1943 to 31st December 1943, there are 108 days.
- From 1st January 1944 to 31st August 1944, there are 244 days.
- From 1st September 1944 to 19th September 1944, there are 19 days.

In total, there are 108 + 244 + 19 = 371 days between 15th September 1943 and 19th September 1944.

Dividing by 7 to find the remainder

To find the day of the week, we need to divide 371 by 7. The remainder will give us the day of the week.

371 ÷ 7 = 53 remainder 0

Since there is no remainder, 19th September 1944 was a Monday.

Therefore, if 15th September 1943 was Wednesday, then 19th September 1944 was Monday.
