This is a calendar of all of the technology related meetups happening in Birmingham. You can subscribe to the full Google calendar.
The easiest way to become part of the Birmingham.IO calendar is to put your event on Meetup. Be sure to tag it with technology and then it will be automatically included in the calendar with no other work required.
If your event isn't on meetup, you can post a message in the Birmingham.IO discussion thread and one of the calendar maintainers can add it for you, or if you're technical you can send a Github pull request to the calendar's list.
