Holidays and Birthdays Web Part
People-centric engagement for your intranet
Project Comet is a small but meaningful way to make work more human. It brings holidays and birthdays into everyday view across SharePoint and Viva Connections—helping organizations pause, rest, and celebrate the people who make the work possible. Designed to deploy in minutes and managed entirely through standard SharePoint lists and permissions, Project Comet removes friction for administrators while creating moments of recognition and connection for employees. Built as an open, community‑first solution and shared freely with no licensing or paywalls, Project Comet is our gift back to the SharePoint community—a reminder that great digital workplaces don’t just help us work better, they help us care for one another too.
