Is Calendar available on Free?

No — Calendar (day/week/month) and time blocking require Premium. [See comparison](/en/pricing).

How is time block different from due date?

Due date is the deadline; time block is the hour slot you plan to work on the calendar — for daily planning.

Does it sync with Google Calendar?

Premium supports external calendar sync (up to 2 accounts). See [Sync & reminders](/en/guides/sync-reminders/).
