1. Core Concept & Syntax
The TODAY()function in Microsoft Excel returns the current date based on your computer's system clock.
=TODAY()
TODAY() requires no arguments. Always leave empty parentheses ().
The result updates automatically whenever the worksheet recalculates or is reopened on subsequent days.
Returns the date integer serial number representing midnight (00:00:00), not the current time of day.
In real business spreadsheets, you never want to manually update today's date every morning to calculate aging invoices or project countdowns.
TODAY() automates this completely!2. 🔥 Live Interactive — Return Current Date
Task: Type =TODAY() in the formula bar to query your system clock and return the live current date:
| # | A (Item) | B (Formula) | C (Evaluated Output) |
|---|---|---|---|
| 2 | Today's Date | =TODAY() | Enter =TODAY() and click Calculate |
3. 🔥 Live Practice — Calculate Days Remaining
Task: Calculate how many days remain until each deadline using =DueDate - TODAY():
| # | A (Task) | B (Due Date) | C (=B2-TODAY()) Days Remaining |
|---|---|---|---|
| 2 | Project Report | 2026-09-04 | =B2-TODAY() |
| 3 | Excel Assignment | 2026-09-01 | =B2-TODAY() |
| 4 | SQL Practice | 2026-09-14 | =B2-TODAY() |
| 5 | Presentation | 2026-08-27 | =B2-TODAY() |
4. 🔥 Practical Deadline Tracker (IF + TODAY)
By pairing TODAY() with an IF statement, Excel automatically categorizes tasks into Upcoming, Due Today, and Overdue:
=IF(B2 > TODAY(), "Upcoming", IF(B2 = TODAY(), "Due Today", "Overdue"))
| # | A (Task) | B (Due Date) | C (Status Badge) |
|---|---|---|---|
| 2 | Project Report | 2026-09-04 | =IF(...) |
| 3 | Excel Assignment | 2026-08-28 | =IF(...) |
| 4 | SQL Practice | 2026-08-27 | =IF(...) |
5. 🔥 Live Interactive — Change The Date Tester
Task: Select or enter different dates (yesterday, today, tomorrow) to see how the status automatically reacts:
6. Practical Business Use Case — Order Tracking (Days Elapsed)
To calculate how many days have passed since an event occurred (e.g. fulfillment aging), subtract the past date from today: =TODAY() - OrderDate.
| # | A (Order ID) | B (Order Date - Editable) | C (=TODAY()-B2) Days Since Order |
|---|---|---|---|
| 2 | ORD101 | =TODAY()-B2 | |
| 3 | ORD102 | =TODAY()-B2 | |
| 4 | ORD103 | =TODAY()-B2 | |
| 5 | ORD104 | =TODAY()-B2 |
7. 🔥 Live Employee Tracker (Continuous Tenure)
Task: Calculate how many days each employee has been with the company:
| # | A (Employee) | B (Joining Date) | C (Tenure in Days) |
|---|---|---|---|
| 2 | Amit | 2026-01-15 | =TODAY()-B2 |
| 3 | Priya | 2026-03-10 | =TODAY()-B2 |
| 4 | Rahul | 2026-06-01 | =TODAY()-B2 |
| 5 | Neha | 2026-08-01 | =TODAY()-B2 |
8. TODAY() vs A Fixed Hard-Coded Date
Understand when to use dynamic formulas versus fixed date entries:
Changes every day automatically. Essential for active countdowns, invoice aging, and project deadline monitors.
Permanently fixed in time. Essential for birth dates, order placement stamps, and historical transaction records.

10. Real Business Scenario — Invoice Aging & Status
Task: Build an automated accounts receivable aging report. Calculate Days Remaining and classify invoices into Overdue, Due Today, and Pending:
| # | A (Invoice ID) | B (Invoice Date) | C (Due Date) | D (Days Remaining) | E (Payment Status) |
|---|---|---|---|---|---|
| 2 | INV001 | 2026-08-01 | 2026-08-23 | — | =IF(...) |
| 3 | INV002 | 2026-08-10 | 2026-09-04 | — | =IF(...) |
| 4 | INV003 | 2026-08-15 | 2026-08-28 | — | =IF(...) |
11. Important Limitations & Best Practices
Keep these fundamental Excel behaviors in mind when designing date-based workflows:
- No Time Component:
TODAY()only provides the date (at midnight). If you need date and time, Excel providesNOW(). - Not a Permanent Timestamp: Because
TODAY()is volatile, opening the file next week will recalculate the formula to next week's date. If you need a permanent creation stamp, press Ctrl + ;. - System Clock Dependency:
TODAY()reads from the local device/server system clock.
12. 🔥 Live Final Challenge: Subscription Monitoring Sheet
Business Requirement: Build the subscription renewal monitor. Calculate Days Remaining and categorize status into Active, Expires Today, and Expired:
| # | A (Subscription) | B (Start Date) | C (Expiry Date - Editable) | D (Days Remaining) | E (Status) |
|---|---|---|---|---|---|
| 2 | Plan A (Annual) | 2026-01-15 | — | =IF(...) | |
| 3 | Plan B (Trial) | 2026-03-20 | — | =IF(...) | |
| 4 | Plan C (Enterprise) | 2026-05-10 | — | =IF(...) | |
| 5 | Plan D (Monthly) | 2026-06-01 | — | =IF(...) |

14. Accuracy & Production Date Arithmetic Rules
Excel stores dates as integer serial numbers (where Day 1 = January 1, 1900). Keep these arithmetic rules in mind:
| Operation | Formula Example | Result Type | Purpose |
|---|---|---|---|
| Future Date Offset | =TODAY() + 7 | Date Serial Number | Calculates the exact date 7 days from today |
| Past Date Offset | =TODAY() - 30 | Date Serial Number | Calculates the date 30 days ago (for 30-day lookback windows) |
| Days Remaining | =DueDate - TODAY() | Integer (Days Count) | Positive for future deadlines; negative for overdue deadlines |
| Days Elapsed | =TODAY() - PastDate | Integer (Days Count) | Number of days that have passed since an event |
