Shareable Calendar for Scheduling

Nittei-san offers several key features that simplify scheduling:

• No registration required: You can start using it immediately without creating an account or logging in.
• Real-time collaboration: All participants can edit the shared calendar simultaneously, making it easy to coordinate.
• Google Calendar sync: If you log in with Google, you can load your own calendar events, which are displayed faintly on Nittei-san's calendar for reference.
• Free-text entry: You can paste and set candidate dates in free-text format, and copy all available time slots to your clipboard.
• Batch member registration: You can register members in bulk via paste, improving efficiency.
• Mobile usability: The tool is optimized for mobile devices, allowing easy access on the go.

Nittei-san is ideal for various scheduling scenarios:

• Organizers: Create a new calendar by pressing the "Start Scheduling!" button, enter potential time slots, add expected members, and share the URL with participants. Once everyone has entered their availability, the scheduling is complete.
• Participants: Receive the URL shared by the organizer, select your name, and enter your preferred dates and times. After finishing, notify the organizer.
• Teams and external partners: It is especially useful when coordinating with people who do not use the same scheduling tools. Instead of manually listing date options, you can simply share the calendar link.
• Immediate use: Since no account or login is needed, it can be used instantly for both internal and external scheduling, without the need for tool implementation.

Nittei-san is free to use indefinitely. There is no account registration, login, or download required. You can use the service without any cost, making it accessible for anyone needing quick schedule coordination.
