Syncing with Google Calendar is easy. It will significantly make your daily time tracking easier, because it will allow you to follow your calendar as a template for the time you spent that day.
Go to your Calendar page (next to your Dashboard) and open the Calendar Settings on the right of the page. Here you will find a list of your Yanomo calendars and “Google Calendar” and “Twitter” headers. Next to the header there is a [+] symbol. Click this and you will be redirected to Google for the appropriate authentication. Once finished your calendars will be loaded and visible in Yanomo. You can hide calendars by deselecting the related checkboxes.
