Twittercal won a Mashup of the Day award back in February by connecting your Twitter account with your Google Calendar. This connection allows you to add events to your calendar simply by sending a direct message.

The process is pretty simple. All you need is a Twitter account and a Google Calendar. Head to twittercal.com and fill in a few boxes. Once you request authorization, you’ll be forwarded over to Google where you need to grant it access. After that, you’re free to start adding events.

To add events, simply send a direct message to @gcal giving the details of the event. Google Calendar is pretty good about interpreting human language, so you can send it readable messages. Here are a few examples:

d gcal metting with paul tomorrow at 7pm

d gcal meeting with fred on monday, 25th of june at 9am

Within minutes, you should see your event added to your calendar. Be sure to check out the FAQ or leave a comment here if you have any questions.

Thanks to Lindsay Rees (@lindsayrees) for the tip on this great little app.
