ELI5: Explain Like I'm 5

Digital calendar

A digital calendar is like a regular calendar, but instead of having it in a book or notebook, it's kept online in a computer. It helps you keep track of things like important dates, events, and appointments by allowing you to save them in one place. You can also share information with other people who also have digital calendars. By having everything online, you don't have to worry about losing it, or forgetting things because it's all stored in one place.
