This repo walks through connecting to the Google Calendar API.
Decision gist · record as of 2026-08-14
No. The package is dormant (last updated 2023-11-30), has incomplete core features (timezone hardcoded, no recurring event support, no invitation handling), and its license metadata is unclear. Unless you need exactly this integration for a prototype and can work around its limitations, consider waiting for active maintenance or exploring alternative approaches.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Google Cloud project setup, Calendar API enabled, and OAuth credentials file (credentials.json) in the specified path.
- Low friction install with a pure Python wheel.
- Maintenance is dormant—last commit was 2023-11-30—so expect no active support or updates for bugs or API changes.

What it is and what it does
Langchain-google-calendar-tools is a LangChain integration that wraps the Google Calendar API, allowing language models to interact with calendar data through a tool interface. It depends on google-api-python-client, google-auth-oauthlib, langchain, protobuf, and pytz to handle OAuth authentication, API calls, and timezone conversions.
The package is in beta (0.0.1) and dormant—its last release and commit were 2023-11-30. The documentation acknowledges incomplete features: timezone is hardcoded to Vietnam's timezone, recurring event updates are unimplemented, and invitation-related functions are missing. It requires manual setup of a Google Cloud project, Calendar API enablement, and OAuth credentials before use.
Use it for
- Embed calendar queries into LangChain agents to let language models fetch upcoming events or check availability
- Build chatbots that can read calendar information in response to natural language questions
- Prototype calendar automation workflows where an LLM decides which calendar operations to perform
- Integrate calendar data into multi-step LangChain chains that need to reference scheduling information
