n8n Webhook Workflow: Office Open Status by Custom Schedule

Get Instant “Office Open/Closed” Answers via an n8n Webhook

This n8n Webhook workflow tells you whether your office is currently open or closed—using a weekly schedule, optional full-day closed dates, overnight hours, and your office’s IANA time zone. Send an authenticated POST request and receive a clear JSON response.

What this workflow does

• Receives an authenticated POST request using an n8n Webhook (Webhook Header Auth credential).
• Loads office configuration, including:
  • Your IANA time zone
  • Weekly opening intervals by weekday
  • An optional list of closed dates (YYYY-MM-DD)
• Calculates local date/time in the configured time zone.
• Determines open status by checking:
  • Today’s scheduled intervals
  • Any overnight interval from the previous day
  • Any full-day closure date
• Returns JSON including open/closed status, local timestamp fields, today’s hours, and closure indicators.

Use cases

• Power an automated “Office Status” check for your customer support app or website widget.
• Route calls/chats differently when the office is open vs. closed, including overnight coverage.
• Disable or label holiday responses using YYYY-MM-DD closed dates—without changing code.

Technical details

• Webhook node for the endpoint (authenticated via Webhook Header Auth credential).
• Code node to calculate local time, apply weekly intervals, handle overnight logic, and evaluate closed dates.
• Sticky Note for workflow guidance.
• Respond to Webhook node to return the JSON result.

Setup note: Replace YOUR_TIME_ZONE with your IANA time zone, configure weekly hours, add closed dates, then test scenarios (open/closed/overnight/closure) before activation.
