Google Calendar's focus time feature allows users to schedule dedicated blocks of time for focused work, helping them avoid distractions and stay productive. This event type is only available on work and school accounts and can be easily set up by selecting the "Focus time" option when creating a new event. Users can customize their focus time events to repeat at specific intervals, decline meeting invitations during that time, and even automate notifications through Google Chat. To make the most of this feature, users should avoid overscheduling, add descriptions for clarity, schedule focus time around their most productive periods, and leverage automation tools like Zapier to streamline workflows.
