\n– We need to find the number of days from March 1st of year Y to February 1st of year Y+1.
\n– The period covers the rest of year Y starting from March 1st, plus January and the first day of February in year Y+1.
\n– Number of days from March 1st (Y) to Feb 1st (Y+1):
\n – March (Y): 31 days
\n – April (Y): 30 days
\n – May (Y): 31 days
\n – June (Y): 30 days
\n – July (Y): 31 days
\n – August (Y): 31 days
\n – September (Y): 30 days
\n – October (Y): 31 days
\n – November (Y): 30 days
\n – December (Y): 31 days
\n – January (Y+1): 31 days
\n – February (Y+1): 1 day (up to the 1st)
\n– Total number of days = 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 31 + 1 = 338 days.
\n– The number of “odd days” is the remainder when the total number of days is divided by 7.
\n– 338 \u00f7 7 = 48 with a remainder of 2.
\n– The number of odd days is 2.
\n– Since March 1st of the starting year is Sunday, February 1st of the next year will be Sunday + 2 days.
\n– Sunday + 2 days = Tuesday.
\n– This calculation does not depend on whether year Y or year Y+1 is a leap year, because the period starts after February 29th in year Y (if it’s a leap year) and ends before February 29th in year Y+1 (if it’s a leap year).
