Dynamically Send Out-of-Office / Vacation Message using Gmail & Google Calendar

Description

What it Does
Automatically checks your Google Calendar to determine if you're officially off work for the rest of today. If so, it auto-sends a personalized out‑of‑office reply via Gmail, telling senders when you’ll be back—based on your next calendar entry within the next 2 weeks.

Prerequisites
To use this template, you'll need:
Gmail credentials (for the trigger and reply nodes)
Google Calendar credentials (for both calendar checks)
A dedicated work calendar selected in the Calendar nodes

Workflow Logic
Gmail Trigger
Monitors incoming emails every minute
Can be filtered (e.g., labels or VIP senders)

Calendar Check #1
Inspects if any events remain today

Calendar Check #2
If no remaining events, scan the next 14 days for the next event

Function Node
Formats the return date as Weekday, Month D, YYYY (e.g., “Thursday, July 24, 2025”)

Gmail Send
Sends a customized out‑of‑office email, using the formatted date
Optionally includes n8n attribution (editable)

User Setup Instructions
Gmail Trigger: Connect your Gmail account and add any desired filters (labels, senders).
Google Calendar Nodes: Connect your calendar account and select your “work” calendar in both nodes.
Function Node: No changes needed unless you prefer a different date format.
Gmail Send Node: Edit the message template and toggle attribution as desired.

Customization - Options
Edit the final email content and tone in the Send node
Adjust calendar lookahead in Calendar Check #2 (default is 14 days)
Add Gmail filters to restrict auto-replies (e.g. only specific senders or labels)

Why It's Useful
Ideal for freelancers, consultants, or remote workers who don’t follow a strict 9–5, yet want automated responses aligned with their actual availability, not a static setting. It’s dynamic, real-time, and easy to tweak.
