2015 - Slack integrated with Google Calendar to keep up with Flowdock

Slack, the popular office communication tool, will now integrate with Google Calendar, letting events automatically post reminders inside slack channels. After linking a Google account to Slack, you can choose any calendar and instruct it to post to certain Slack channels. For example, you could have events from your company’s development deadline calendar post reminders to the #dev channel two days before a product deadline. Or, on a more lighthearted note, you could have your company’s birthday or holiday calendar automatically post to #general so your whole team can celebrate together. The integration will also allow daily or weekly calendar summaries to be sent out to everyone subscribed to a certain Slack channel.
