Notion Calendar, formerly known as Cron, is a free calendar application acquired by Notion in 2022 and relaunched in January 2024 as a deeply integrated scheduling tool for the Notion ecosystem. Known for having one of the most beautifully designed calendar interfaces, Notion Calendar bridges the gap between time management and project management by allowing users to display Notion database items directly on their calendar. Any Notion database with date properties can be viewed as calendar events, and users can link calendar events to Notion pages for seamless context switching. The scheduling links feature lets users set availability windows and share booking links, enabling others to self-schedule meetings without back-and-forth emails. With the launch of Notion 3.0 in September 2025, the platform gained AI Agent capabilities that can work autonomously for up to 20 minutes, helping with scheduling optimization and task management. Notion Calendar integrates natively with Google Calendar and offers a polished iOS mobile experience. The app supports multiple calendar views, time zone management, and menu bar quick access on desktop. While it excels as a free, elegant calendar solution for Notion users, it currently lacks Outlook integration, Android support, and advanced features like automatic task scheduling or capacity planning. For teams already invested in the Notion ecosystem, Notion Calendar provides a natural extension for time management, with the Business plan at $20/month unlocking full AI access powered by GPT-4.1 and Claude 3.7 Sonnet for enhanced scheduling intelligence.
