There are 52 weeks in a year. To be more precise:

• A common year has 365 days.
• Since one week has 7 days, 365 ÷ 7 ≈ 52.14 weeks.
• This means there are 52 full weeks and 1 extra day.
• In a leap year (366 days), there are 52 weeks and 2 extra days.

So, generally, a year is considered to have 52 weeks.
