What is Advanced Calendar?
The Advanced Calendar skill transforms how you manage your time by integrating a sophisticated natural language processor directly into your workflow. It allows you to schedule meetings, set reminders, and query your agenda using everyday language, eliminating the need for complex syntax. Designed as a core component for Openclaw Skills, it bridges the gap between conversational AI and practical time management.
This skill doesn't just store dates; it actively ensures you stay on track through an intelligent reminder system. It supports various notification channels including WhatsApp, Discord, and Telegram, featuring a persistent snooze mechanism that repeats alerts every 15 minutes until you acknowledge them, ensuring important tasks never slip through the cracks.
Advanced Calendar Use Cases
- Rapidly scheduling complex meetings using conversational prompts.
- Receiving persistent notifications via WhatsApp or Discord for critical appointments.
- Generating automated daily morning summaries of all scheduled tasks.
- Managing a local, private calendar without relying on external cloud providers.
- Using voice or text to check availability and agenda for specific timeframes.
How Advanced Calendar Works
- The user provides a natural language input or structured command to the agent.
- The Natural Language Processor identifies the intent (create, list, update, etc.) and extracts relevant entities like dates, times, and durations.
- If required information is missing, the Interactive Handler prompts the user for specific details.
- Events are stored in a local JSON-based persistent storage layer for privacy and speed.
- The Cron Integration regularly checks for upcoming events and triggers notifications through configured channels.
- The Persistent Reminder Engine monitors for user acknowledgments, repeating notifications every 15 minutes if no response is received.
Advanced Calendar Setup
To install the skill, use the following command in your terminal:
clawhub install advanced-calendar
After installation, configure your preferred notification channels (WhatsApp, Telegram, etc.) and set up an optional automated daily summary at 9:00 AM using the OpenClaw cron system:
openclaw cron add \
--name "daily-calendar-summary" \
--schedule "0 9 * * *" \
--command "calendar daily-summary"
