JUG meetups are pulled from the calendar each group publishes, via the community-run
World Wide JUGs
directory, and refreshed daily. If your JUG is missing or its events
aren't showing up, add or fix its entry there — it appears here automatically.
Conferences, workshops and other one-offs have no such feed, so they are added by
pull request: one small
YAML file per event .Last synced 18 September 2026, 06:02 UTC. 8 groups could not be synced last time: Budapest JavaBár, Java User Group Augsburg, Java User Group Duesseldorf Rhein, Java User Group Freiburg, Java User Group Kaiserslautern, Java User Group Mainz, Java User Group Switzerland, Nairobi Java User Group.
