What day of the week was 1st March 2008?
easy Q2 of 15
Step-by-Step Solution
Step 1: Inputs (March — no year change)
q = 1,m = 3,year = 2008.Step 2: Compute K and J
K = 2008 % 100 = 8,J = floor(2008 / 100) = 20.Step 3: Evaluate components
floor(13*(m+1)/5) = floor(13*4/5) = 10;floor(K/4)=2;floor(J/4)=5;5*J = 100.
Sum:h = (1 + 10 + 8 + 2 + 5 + 100) = 126→126 mod 7 = 0.Step 4: Map result to weekday
0 → Saturday(Zeller mapping). So 1 Mar 2008 = Saturday.Final Answer:
Saturday → Option BQuick Check:
Calendar references confirm 1-Mar-2008 = Saturday ✅
Quick Trick: For March–December you don't change the year; compute month-term and reduce mod 7.
