How to Calculate Dates Using Weeks
Method 1: Calendar Calculation
Count forward or backward week by week on a calendar. Each week equals 7 days. This method is simple but can be time-consuming for larger numbers of weeks.
Method 2: Mathematical Calculation
Multiply the number of weeks by 7 to get the total days, then add or subtract from your start date. This method is faster and more accurate for longer time periods.
