Number of odd days in a normal year is 1 and number of odd days in a leap year is 2.
There are 4 normal years (2023, 2025, 2026 and 2027), 1 leap year i.e., 2024 from February 8, 2022 to February 8, 2027
So, number of odd days will be
From February 8, 2022 to February 7, 2023: 1 From February 8, 2023 to February 7, 2024: 1
From February 8, 2024 to February 7, 2025: 2
From February 8, 2025 to February 7, 2026: 1
From February 8, 2026 to February 7, 2027: 1
So, total number of odd days = 6 So, on February 8, 2027 it will be Monday
