This question is often asked by people when talking about the length of a year or about the leap years system. The exact answer to this question can vary, as there are multiple types of calendars across the world. So, the answer to this question “how many weeks in a year” can be quite difficult to answer. Because there are so many types of calendars nationally and internationally. Some calendars depend on the movement of the season and some depend on the lunar circle. While Gregorian calendar depends on the movement of earth completing a round trip across its voyage around the sun. Gregorian calendar is used as an international standard all around the world for the measurement of the month and date and years. In the Gregorian calendar, there are 365 days and 6 hours to be exact a year. Otherwise also considered as 365 days for three years and the fourth year in a leap year and has 365 days, making February a 29 days month once every four years.
So, when we divide 365 with 7 as our week has seven days, then we get an answer that is 52.1428 weeks per year. I know this doesn’t make sense as we have our weeks, not in exact but in the fraction. But this is the exact time earth completes its circle around the sun. Every year in most calendars have 12 months and each month has almost 4.25 weeks in a month. The only February in the three years in the Gregorian calendar has exacly4 weeks as it is for 28 days. I gave priority to the Gregorian calendar in answering the question of how many weeks are in a month, as this is a standard calendar across the world. In most of the places, it is the only calendar and Governments rely on it.
But there are also some other calendars as well. Such as Hijri Calendar, widely used by countries with Muslim populations. They use it as their standard calendar also sometimes use it as their secondary calendars. This calendar depends on the moon or Lunar circle completion. Every month can have almost 28 to 30 days and they have 355 or 354 days per year. So, the weeks in a Hijri calendar are different from the number weeks in the Gregorian calendar. Every Islamic or Hijri Calendar has almost 50.64 weeks per year.
Hindu Calendar is a mixed calendar based on the movements of the earth, sun, and moon. This is one of the most ancient calendars being used to date. This calendar also has 365.6+ hours in every of its circle. This calendar is like the Gregorian calendar but is not used worldwide. Every year in Hindu Calendar has 52.15 weeks per year.
There are many other calendars such as the Chinese calendar and Egyptian calendar as well as Japanese and Korean calendars. Every Chinese year has almost 50 weeks per year and like the Egyptian and Japanese and Korean. They all have almost 50.60 weeks per year. They all are based on the Lunar cycle, so they give the same results.
From the discussion above it can be said that the Gregorian calendar and Hindu have 52.14 weeks and other calendars based on the lunar cycles have 50.60 weeks per year.
