There are 1,461 (365x4+1) days between one February 29 (leap day) to the next.
1461 is 208 weeks with a 5 day remainder, so each leap day will fall five days after the previous one.
Since 5 is not a factor of seven (number of days in the week), it will take 7 leap years (that is 28 years) for there to be a repeat in the day of the week.
So, 2028, 2056, and 2084 will have a leap day on Tuesday. Since the century began in 2001 and not 2000, the answer is 3.
