If 1st July 2022 was Sunday, then what was the day on 1st November 2022?

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 $123 \mod 7$:

$123 = 17 \times 7 + 4$

So $123 \mod 7 = 4$

---

Starting from Sunday (July 1) and moving forward 4 days:

Sunday $\to$ Monday $\to$ Tuesday $\to$ Wednesday $\to$ Thursday

Therefore, November 1, 2022 was Thursday.

The correct answer is Option 3: Thursday.
