This automatically provides the number of days remaining until my special day. If my birthday has already occurred this year, I add 1 to the year part of my birth date to calculate the countdown to my next birthday.

Reminders and Alerts

Excel can be used to set up reminders and alerts as the birthday approaches. Excel cannot sedn notification, but conditional formatting can be used to change the color of the cell when the date approaches.

Under conditional formatting, you can set rules such as “If the number of days is less than 10, turn the cell background color to red,” signaling that the date is close.
