Why Calculate 90 Days From a Date?
Understanding how to calculate a date that is a specific number of days in the future can help you in numerous scenarios. For instance:
- Project Management: Establishing deadlines for deliverables.
- Finance: Calculating payment due dates.
- HR Management: Tracking employee leave or sick days.
Basic Date Calculation in Excel
Excel offers a simple and effective way to perform date arithmetic using its built-in date functions. Here are the steps to calculate 90 days from a given date.
Step 1: Open Excel
Start by launching Microsoft Excel on your computer. Create a new worksheet or open an existing one where you want to perform your calculations.
Step 2: Enter Your Start Date
Choose a cell where you want to enter your initial date. For example, you could enter the date 2023-10-01 in cell A1. Make sure to format the cell as a date if it does not automatically recognize it.
Step 3: Use the Formula to Add 90 Days
In the next cell, use a simple formula to add 90 days to the date you've entered. The formula would look something like this:
=A1 + 90
Step 4: Press Enter
After entering the formula, press Enter. The cell will now display the date that is 90 days after the initial date. For instance, if your start date was 2023-10-01, the result would be 2024-12-30.
Understanding Date Formatting
Excel automatically formats dates in a default manner. However, you can change the format to suit your preferences. Here’s how to do it:
Step 1: Select the Date Cell
Click on the cell that contains the date you want to format.
Step 2: Format Cells
Right-click and select Format Cells from the context menu. You can also navigate to the Home tab and click on the Number Format dropdown menu.
Step 3: Choose Date Format
In the Format Cells dialog, select Date from the list and pick your desired format. Click OK to apply.
Using the EDATE Function
Another method to calculate a date 90 days from a start date is by using the EDATE function, which is particularly handy if you need to calculate a date a specific number of months ahead, but it can also be adapted for day calculations.
Step 1: Enter the Formula
In a new cell, enter the following formula to add approximately 3 months:
=EDATE(A1, 3)
Important Note
The EDATE function adds months rather than days. If you strictly want to add 90 days, stick with the original addition method. If you are interested in months, EDATE is perfect! 📅
Handling Workdays with NETWORKDAYS
In some cases, you might want to calculate only business days (excluding weekends and holidays). For this, Excel provides the NETWORKDAYS function.
Step 1: Use the NETWORKDAYS Formula
=NETWORKDAYS(A1, A1 + 90)
Important Note
This function can also take additional arguments to account for holidays, providing even more accurate results when calculating deadlines that only involve working days. 🎯

To help visualize what we’ve discussed, here’s a summary table of the functions used for date calculations in Excel:

Additional Tips and Tricks
- Use Date Picker: In recent versions of Excel, you can click on a date cell to use a date picker, making it easier to select dates visually. 📆
- Keyboard Shortcuts: Familiarize yourself with keyboard shortcuts for quicker navigation. For instance, Ctrl + ; will insert the current date.
