How many days are there from February 7, 2011 to August 21, 2012?

How many days are there from February 7, 2011 to August 21, 2012?

2011 is not a leap year, so there are 365 days to February 7, 2012 (excluding February 7, 2011)
Then 2012 is a leap year (a multiple of 4, not a multiple of 100)
So February has 29 days
It will take another 22 days until February 29
Then March, April, may, June and July
31+30+31+30+31
August 21 plus 21
altogether
365 + 22 + 31 + 30 + 31 + 30 + 31 + 21 = 561 days (excluding February 7, 2011)
If so, 562 days (including February 7, 2011 and August 21, 2012)
