Ever since we launched Google Calendar, people in our forum have been pretty vocal about a missing piece -- an integrated task list. "To-do would be tooo-rific," "I really, really, really need to use a to-do list," and my favorite: "I'll join your team to help you get it done!" The rumble turned into a roar a few months ago when we launched Tasks in Gmail Labs. Now we've integrated Tasks into Google Calendar as well.

To get started, open Calendar and click on the "Tasks" link on the left hand side. You'll see the familiar task list you're used to using in Gmail, with some Calendar-specific additions:
  • Tasks that have due dates will automatically appear on your calendar. To create a task with a due date in Calendar, click on an empty space in month view or the all-day section of week view, and be sure select the "Task" option.

  • To attach a due date to an existing task, click the right-arrow from within the task list, and then click on the calendar icon.
  • You can modify a task's due date by dragging it to a different date, just as you would with a regular calendar event.
  • To mark a task completed from within Calendar, just click on the task's checkbox. (Isn't that satisfying, overachievers?)
  • To keep track of due dates before they arrive, there's a nifty new "Sort by due date" feature available in the Actions menu at the bottom of your task list. While sorting by due date, you can reschedule a task by clicking on it in your list, then pressing control and the up or down arrow key.

While working to help bring this feature to you, I used it to keep track of my own tasks. Now I can finally check off the last one in that list: "write blog post." Phew.
