To see who has a birthday or work anniversary in Matter and who is missing one, download the member template in the web app under Settings, Celebrations.
Who can use this: Workspace Owners and Admins on the Basic plan and above, or on any plan during the free trial. Works the same for Slack and Microsoft Teams workspaces.
For an overview of the whole feature, read the Celebrations Guide. Related articles: Customizing the coin amount per work anniversary year and Removing a birthday or work anniversary date.
Open the Web App.
Go to Settings, then the Celebrations section.
Open Birthdays or Work Anniversaries, then click Download Template. This will download a file of all workspace members showing what dates have been added, and who is missing a date.
Fill in the missing dates and re-upload.
Note: To remove an unwanted date, see Removing a birthday or work anniversary date.
