How many weeks in a year?‍

Calculate weeks in a year.

Approximate Answer: 52 weeks

Exact Answer: 52.143 weeks for a regular year, 52.286 weeks for a leap year.

Weeks in a regular year

1 regular year = 365 days.

1 week = 7 days.

Hence,

1 regular year

= (365 days) / (7 days/week)

= 52.143 weeks.

= 52 full weeks & 1 additional day.

Weeks in a leap year

A leap year occurs every 4 years except for years that are divisible by 100 and not divisible by 400.

Steps to determine if a year is a leap year:

1) Is the year divisible by 400? YES = LEAP YEAR, NO = GO TO STEP 2.

2) Is the year divisible by 4? YES = GO TO STEP 3, NO = NOT A LEAP YEAR.

3) Is the year divisible by 100? YES = NOT A LEAP YEAR, NO = LEAP YEAR.

1 leap year = 366 days.

1 week = 7 days.

Hence,

1 leap year

= (366 days) / (7 days/week)

= 52.286 weeks.

= 52 full weeks & 2 additional days.
