Understanding the Fundamentals of Date Functions
When working with date calculations in Excel, understanding the fundamentals is key to achieving quick and accurate outcomes. Excel treats dates as serial numbers, which makes them ideal for arithmetic operations. Dates begin from January 1, 1900, designated as serial number 1, and increase sequentially.
Grasping this concept is essential for effectively using Excel's date functions. With this knowledge, you can effortlessly add or subtract days to calculate new dates.
Leveraging Excel's Capabilities for Swift Date Results
Leveraging Excel's capabilities for quick date calculations is not only a time-saver but also a game-changer. You can use tools like conditional formatting to highlight important dates, alerting you when a deadline or milestone is 90 days away.
Additionally, Excel offers a wide range of formulas, from the simple TODAY()
function to more advanced ones like WORKDAY()
and NETWORKDAYS()
, allowing for precise task management. Whether you're planning for future events or ensuring you meet time-sensitive deliverables, Excel provides an easy way to stay on schedule.

.
STEP 1: Enter the TODAY() function in cell A2.
STEP 2: In cell B2, input this formula, and Excel will automatically calculate the date 90 days from today.
This method is perfect for planning a quarter ahead, setting personal milestones, or scheduling work projects. It removes the need for manual counting, providing instant and accurate results.
Calculating 90 Days in the Past
Calculating 90 days in the past is just as easy as looking forward. Use the formula =TODAY()-90
to find the date 90 days before today.
This is useful for analyzing historical data, reviewing past performance, or recalling important dates. With this simple subtraction formula, you can navigate your timeline backward with the same ease as moving forward.
Practical Uses of 90-Day Calculations
Financial Forecasting and Planning with 90-Day Projections
For financial professionals, the ability to project 90 days into the future is vital. Whether it's identifying loan maturity dates, setting payment deadlines, or planning investment horizons, Excel is an invaluable tool.
Use the EDATE
function to forecast a quarter ahead, enabling you to see upcoming financial outcomes or necessary actions. For example, =EDATE(TODAY(),3)

This function is crucial for financial forecasting and planning, helping you stay proactive and prepared for future financial scenarios.
Monitoring Project Deadlines and Milestones
Using Excel to track project deadlines and milestones is straightforward with the 90-day calculation technique. Set your key dates and use formulas like =PROJECTSTART 90
