# What Is Calendar?
> DingTalk Calendar is a time-management tool linked to chats, mail, and To Do—covers precise event notifications, auto meeting-group creation, and day/week/month/three-day views.
DingTalk Calendar is a time management tool that connects chats, mail, and To Do. It helps reduce communication costs and makes team collaboration smoother and more efficient.
## Precise event and meeting notifications
Create meeting events with one click. Invitations are sent directly to each participant in chat, so everyone receives the information reliably.
## Automatically create a meeting group
Events can automatically generate a meeting group, making organization, communication, and collaboration before and after the meeting more efficient.
## Multiple calendar views
In addition to day, week, and month views, DingTalk Calendar also provides a three-day view that is better suited for mobile. This makes it easier and more efficient to view schedules and plan time.
