The correct answer is 52. There are approximately 52 weeks in a year. A week is any period of seven consecutive days. It begins with either Sunday or Monday. A month is usually subdivided into Weeks. A year, whether leap year or regular year has 12 months and 52 weeks.
A regular year has 365 days, and a leap year has 366 with an extra day in the month of February. If you divided 365 by 7, you would get 52.1428571 weeks, and if you divided a leap year (366 days) by 7, you would get 52.2857 weeks, which is still approximately 52 weeks. The only calendar that has less than 52 weeks is the lunar year. A lunar year has 354.37 days making 50.6242857 weeks.
One year has almost 52 weeks and one day (unless it is a leap year). Basically, one common year has 365 days and there are 7 days in a week. So, to attend the total number of weeks per year, we need to find the ratio between the number of days (365) in a year to the number of days (7) in a week.
i.e. 365 / 7 = 52 weeks and 1 day.
Now, if it is a leap year, then it has 366 days. So, divide 366 by 7 and you will get 52 weeks and two days.
One year has approximatly 52 weeks. One calendar common year has 365 days: 1 common year = 365 days = (365 days) / (7 days/week) = 52.143 weeks = 52 weeks + 1 day. One calendar leap year occures every 4 years, except for years that are divisable by 100 and not divisable by 400.
One calendar leap year has 366 days, when February has 29 days: 1 leap year = 366 days = (366 days) / (7 days/week) = 52.286 weeks = 52 weeks + 2 days. This is viable to anyone, thus we can calculate easily the days, hours, weeks, seconds, and etc.
