The starting day is July 1, 2022, which is Sunday. The task is to find the day on November 1, 2022.
To find the day, we need to count the total number of days between July 1 and November 1.
Days from July 1 to November 1:
- July 1 to August 1: 31 days
- August 1 to September 1: 31 days
- September 1 to October 1: 30 days
- October 1 to November 1: 31 days
Total days =31+31+30+31=123 days
To find the day of the week, we calculate 123mod7:
123=17×7+4
So 123mod7=4
Starting from Sunday (July 1) and moving forward 4 days:
Sunday → Monday → Tuesday → Wednesday → Thursday
Therefore, November 1, 2022 was Thursday.
The correct answer is Option 3: Thursday.
