Our calendars should help us make the most of our time — scheduling meetings at work, remembering brunch with friends, and keeping track of all our other commitments. But often our to-do list is elsewhere, separate from the Calendar that organizes our day, and we end up overcommitted or miss something important because we forgot to check our list.
Now there’s a single way to manage your day: starting this week, you can create Reminders in Google Calendar to keep track of your to-dos alongside your scheduled events.
