Google Calendar Listing Workflow
This workflow fetches a list of upcoming events from your Google Calendar using a search query and summarizes the results using AI.
Note:
This workflow uses two AI Data Processing nodes, each with a tool, because the output of the first tool (Date/Time Now) is required as input for the second tool (Google Calendar Fetch Events).
Current smaller models (≤ 8B parameters) are not able to call the available tools sequentially—they attempt to call both tools at the same time, which leads to incorrect results.
If you use a larger LLM (more than 8B parameters), you can combine both tools in a single AI Data Processing node, as larger models can more reliably call tools one after the other.

- Data Source
- Input:
"Get me the next 3 calendar events coming up."
- Input:
- AI Data Processing (Date/Time Context)
- Prompt: Augments the original request with current date and time information using the dateTimeNow tool
- Tool: Date/Time Now Tool
- Model: llama3.1:8b
- AI Data Processing (Calendar Fetch)
- Prompt: Fetches calendar events using gcalendarFetchEvents tool and formats the output
- Tool: Google Calendar Fetch Events Tool
- Model: llama3.2:3b
- Data Flow Spy
- Output: Displays the final list of upcoming calendar events
- (Optional) Data Flow Spy
- Output: Used for inspecting intermediate data (time-augmented request)
Steps
- Provide Input: The workflow starts with a Data Source node that supplies the prompt: "Get me the next 3 calendar events coming up."
- Add Date/Time Context: The first AI Data Processing node uses the Date/Time Now Tool to obtain the current date and time, then augments the original request with this temporal context.
- Fetch Calendar Events: The second AI Data Processing node receives the time-augmented request and uses the Google Calendar Fetch Events Tool to retrieve the upcoming events, then formats the results.
- Display Result: The Data Flow Spy node displays the final formatted list of calendar events.
- (Optional) Inspect Intermediate Data: An additional Data Flow Spy node can be used to inspect the time-augmented request between the two AI processing steps.
