The page shows January 2027 with the 23rd circled. Using odd days, find the day of the week on 23 January 1897, the birthday of Netaji Subhas Chandra Bose.

1897 to 2027 is 130 years. The 29 Februaries crossed are those of 1904, 1908, …, 2024: 31 of them (1900 is NOT a leap year, 2000 is). Odd days $=130+31=161=23\times 7$ exactly, so the day is the same as in 2027: Saturday. (Friday counts 1900 as a leap year.)
