We are spread around the globe, if you want you can share your timezone on Timezone.io to make it easier to coordinate with people. You can find people’s timezone on https://timezone.io/team/opennms-community.
If you want you can join the OpenNMS community. You don’t have to share your exact location, you can just use something generic like (Europe/Berlin) in your profile settings and a nickname. You can also select, just show my local time if you want to be fuzzier.
There is an annual get-together called DevJam, which is a one-week un-conference to discuss, develop, teach, and learn various topics with and around OpenNMS. You can watch the Events section in Discourse to get notified when we announce upcoming events.
