Collaborating to build an opt-in campaign feature to celebrate Wikipedia’s 25th birthday

Birthday mode is now available -- 16 Feb 2026

This campaign feature is in a soft launch period from 16 February to 22 February, while we test the feature out, fix technical issues and communities explore and tailor it for their language wikis.

The feature will be off by default for readers. From 23 February, communities will be able to turn this feature on by default for readers of their language wiki. On the same day, we will update this page on the Wikimedia Foundation website with instructions for readers.

The feature will be available till 6 April 2026.

Information for admins:

You can now turn on the feature as well as configure it by visiting "Special:Community Configuration” on your wiki. Note that you won’t be able to turn it on by default for readers just yet.

Information for readers:

If you’re visiting Wikipedia in any of the language Wikipedias listed below and you are curious about the “Birthday mode (Baby Globe)” switch in the Appearance Settings on Desktop and Settings on Mobile – well done! You just found a semi-secret easter egg! Turn it on and see if you can find Wikipedia’s 25th birthday mascot as you explore Wikipedia.
