Weeks between two dates calculation:
To calculate the number of weeks between two dates, you can use the following formula:
- End Date: The later date.
- Start Date: The earlier date.
- Weeks: The total number of weeks between the two dates.
Weeks = (End Date − Start Date) ÷ 7
Note: But in JavaScript it is calculated as follows:
- Dates to Milliseconds: Subtract the start date from the end date to find the difference in milliseconds.
- Milliseconds to Days: Divide the difference by 1000 × 60 × 60 × 24 to convert milisecond into days.
- Days to Weeks: Divide the total number of days by 7 to get the number of weeks.
Days = Diiference ÷ (1000 × 60 × 60 × 24)
Then, Weeks = Days ÷ 7
This is how you can use the formula to calculate the number of weeks between two dates.
