UPSC CISF-AC-EXE – 2017
A normal year (365 days) has 365 mod 7 = 1 odd day.
A leap year (366 days) has 366 mod 7 = 2 odd days.
The period from 1st November 2019 to 1st November 2022 spans three full years: the period covering 2020, the period covering 2021, and the period covering 2022 up to Nov 1.
– From Nov 1, 2019 to Nov 1, 2020: This period includes the entire year 2020, which is a leap year (divisible by 4). Thus, this period adds 2 odd days.
– From Nov 1, 2020 to Nov 1, 2021: This period includes the entire year 2021, which is a normal year. Thus, this period adds 1 odd day.
– From Nov 1, 2021 to Nov 1, 2022: This period includes the entire year 2022, which is a normal year. Thus, this period adds 1 odd day.
Total odd days from 1st November 2019 to 1st November 2022 = 2 (from 2020) + 1 (from 2021) + 1 (from 2022) = 4 odd days.
Starting from Friday, we move forward by 4 days:
Friday + 1 day = Saturday
Saturday + 1 day = Sunday
Sunday + 1 day = Monday
Monday + 1 day = Tuesday
So, 1st November 2022 is a Tuesday.
