- For 2000 years =0 odd days
For 10 years 2 leap years and 8 ordinary years :(2*2)+(8*1)
leap year has 2 odd days and ordinary year has one odd day
So total odd days upto 2010 = (0+12)=12
January +February =(31+14)=45
45/7=6
So 3 odd days
Total number of odd days= 12+3=15
15/7=2
Therefore 1 odd day
sunday - 9 years agoHelpfull: Yes(0) No(0)
