A torn calendar page from October 2024 is shown. Using it and odd days, find the day of the week on 2 October 1869, the day Mahatma Gandhi was born.

2 October 2024 is a Wednesday. The 155 years back to 1869 contain 38 leap days (1872–2024, but 1900 is not a leap year): $155+38=193\equiv 4$ odd days. Wednesday $-4$ = Saturday. (Counting 1900 as a leap year gives Friday.)
