Highlight overdue tasks, deadlines and expiration dates using Conditional Formatting

Hard to keep up with deadlines and due dates? Managing projects, inventory, or client renewals all cost time and money for expired dues. But Microsoft Excel comes with a nifty trick: conditional formatting that highlights all past-due dates automatically so you never lose sight of what matters.

In this lesson, you will learn how to make Excel color-code expired dates at once. Best of all, it keeps updating automatically daily all by itself, using just a simple formula that requires no complicated macro or coding. 


📅 Why Use Conditional Formatting for Expired Dates? 

  • Instant visual alert for overdue deadlines
  • Track important dates in real time via TODAY()
  • Increase accuracy in time-sensitive reports
  • Trigger automatic reminders of tasks, payments, certifications
  • Promote task management, for styling, and the reduction of manual errors

🔧 How To Highlight Expired Dates-Step-By-Step Guide in Excel

Say you have the following items with their expiration dates:

Task
Due Date
File tax return
2025-06-20
Client invoice
2025-07-01
Submit Report
2025-06-15

Step 1: Select the cells with dates

Highlight the range where due dates are entered, say B2:B4

Step 2: Apply Conditional Formatting

  1. Go to Home -> Conditional Formatting -> New Rule
  2. Choose “Use a formula to determine which cells to format”
  3. Enter this dynamic formula: =B2<TODAY()
  4. Click Format -> Fill, choose red or orange to show urgency
  5. Press OK to apply the rule

Boom! Now every overdue item is visually marked the moment the date has passed.


Advanced variations for better insight into data

  • Highlight those within the first 7 days of upcoming deadlines: =AND(B2>=TODAY(), B2<=TODAY()+7)
  • Use the icon sets (check marks, warnings, crosses) for easy review:
  • Differentiated by urgency: Red = Overdue, Yellow = Due Soon, Green = Completed.
  • Use in conjunction with filters to show only overdue tasks.

💡 Where This Feature Shines

  • Project Management Dashboards
  • Invoice and Billing Trackers
  • Employee Training or License Renewals
  • Event Planning and Reminders
  • Subscription and Contract Expiration Alerts

🎯 Benefits for Every Excel User

  • Saving time with automatic alerts
  • Improving data accuracy and follow-up
  • Making spreadsheets interactive and intelligent
  • Giving you the ability to make proactive decisions

Do not let absurd deadlines fall through the cracks: Use Microsoft Excel's very powerful conditional formatting to track expired data and upcoming dates. It's such a simple feature, yet so much value in just one rule, and you're managing time like a pro.

Add it to your workflow and watch your spreadsheets come to life with built-in awareness!
