Yes there are 52 weeks in every year.
Actually though we have 52 weeks and 1 day in every year which equals the 365 days we have in the year.
Well if you count the weeks in a month and multiply that by 12 months you would get 48 weeks instead of 52 weeks in a year.
However the actual weeks in a month do vary even though it seems that there are 4 weeks in every month which is not really true.
So we do have 52 weeks in a year and usually yes every year should have 52 weeks.
I used to think that we did actually only have 48 weeks in a year but I was told different by a friend who is a teacher.
I then studied up on it myself and yes there are 52 weeks in a year.
Because if you take 7 days which equals a week and multiply that by 48 weeks then you would get only 336 days.
But if you take 7 days and multiply that by 52 weeks then you would get 364 days but we do have one day over just 52 weeks in a year.
So we actually have 52 weeks and 1 day in a year.
