Let’s dive in!
Step-by-Step Tutorial on How to Calculate Days in Excel
In this tutorial, we’ll walk through how to calculate days between two dates using Excel formulas. By the end, you’ll know how to manipulate dates like a pro!
Step 1: Open Excel and Enter Data
Open Excel and type your starting and ending dates in two separate cells.
For example, enter the start date in cell A1 and the end date in cell B1.
Step 2: Subtract the Dates
In a new cell, type the formula =B1-A1 to find the difference between the two dates.
This formula will give you the number of days between the two dates. Make sure both cells are formatted as dates.
Step 3: Calculate Days Including Weekends
Use the formula =NETWORKDAYS(A1, B1) to calculate the number of working days between two dates.
This formula excludes weekends, counting only weekdays.
Step 4: Add or Subtract Days
To add days to a date, use the formula =A1+10. To subtract days, use =A1-10.
This is useful for setting deadlines. Adjust the number 10 to whatever number of days you need.
Step 5: Calculate Specific Weekdays
Use =NETWORKDAYS.INTL(A1, B1, "0000011") to exclude specific days like weekends or holidays.
In this example, the formula will exclude weekends. You can customize it to exclude different days.
Once you finish these steps, you’ll have your desired calculations displayed in your Excel sheet.
