There are about 208 weeks in 4 years including a leap year but each year has an extra day but a leap year would have two extra days (208 weeks + 6 days about).
25 weeks and 6 days in a normal year and 26 weeks in a leap year.
14 weeks and 5 days in a normal year and 14 weeks and 6 days in a leap year.
25 weeks and 5 days in a normal year and 25 weeks and 6 days in a leap year.
22 weeks and 5 days in a normal year and 22 weeks and 6 days in a leap year.
For the 6 months of January, February, March, April, May and June, there are 25 weeks and 6 days in a normal year and 26 weeks in a leap year.
52.177457 WeeksOr52 Weeks and 1 day with just under 6 hours*Assuming its not leap year
312 weeks is just under 6 years because a year has 52 weeks and 1 day in an ordinary year, and 52 weeks and 2 days in a leap year. 312 divided by 52 is 6.
There are 5 years in 260 weeks, since there are 52 weeks in one year
There can be 260 weeks (and 6 days) or 261 weeks in 5 years. Given the fact that a normal year has 52 weeks and 1 day, and a leap year has 52 weeks and 2 days, 5 years can either be 260 weeks and 6 days, or 261 weeks, depending on how many leap years occur in those 5 years.
Adding 3 weeks to February 14 on a non-leap year gives March 7. On a leap year, this would give March 6.
A leap year occurs once every four years. In six years, there is one leap year. A leap year has 366 days, instead of the normal 365. Therefore, do the following: (365 * 5) + 366 = 2,191
