Calculate Employee Probation End Date

I need to automatically calculate the date 90 days after an employee's start date to schedule their review.

formula.xlsx
=DATE(YEAR(B2), MONTH(B2), DAY(B2) + 90)

How it works: Excel's DATE function constructs a date from separate year, month, and day components. By extracting the year and month from the employee's start date (B2) and adding 90 to the day component (DAY(B2) + 90), the DATE function correctly calculates the date 90 days later. Excel automatically handles month and year rollovers, ensuring accuracy even when the 90-day period spans across different months or years.

Data Setup

Employee Name Start Date Probation End Date
Alice Smith 2023-01-15
Bob Johnson 2023-02-01
Charlie Brown 2023-03-10

Step-by-Step Guide

1

Enter your employee data, including 'Employee Name' and 'Start Date', into an Excel worksheet. Ensure 'Start Date' is in column B, starting from row 2.

2

In the cell where you want the 'Probation End Date' (e.g., C2), enter the formula `=DATE(YEAR(B2), MONTH(B2), DAY(B2) + 90)`.

3

Press Enter to see the calculated probation end date.

4

Drag the fill handle (the small square at the bottom-right of cell C2) down to apply the formula to all other employees.
