A birthdays and anniversaries web part for SharePoint
Birthdays and work anniversaries are the easy wins on an intranet. People like to be seen. Modern SharePoint does not show them, so here is a web part that does.

It reads a SharePoint list. The person name is the Title, the date is a date column named CelebrationDate, and a text column named CelebrationType holds either Birthday or Work anniversary. An optional Person column named Person gives you the profile photo. The Provision-IntranetLists.ps1 script creates the Celebrations list.

In the property pane you point it at the Celebrations list, set how many people to show, and choose a profile photo or initials. It sorts by the date so the next celebration is at the top.
The Celebrations web part is part of my open source SPFx Intranet Suite, a set of web parts for a modern SharePoint intranet. Install the package once and it shows up in the toolbox under Intranet Suite.
