To calculate the number of weeks between two dates in Excel, you can use a simple formula: =(END_DATE - START_DATE)/7. Replace END_DATE and START_DATE with the actual cell references containing your dates (for example, =(B2-A2)/7). This formula subtracts the start date from the end date to find the difference in days and then divides by 7 to convert that number into weeks. For more accuracy, you might round the result using the ROUND function, such as =ROUND((B2-A2)/7, 0).
