Building ‘Out of Office’ Logic in n8n (That Actually Sells).

Standard auto-replies are boring. I’ll show you how to build a ‘Weekend Router’ in n8n. It detects the day (Saturday/Sunday) and switches the LLM system prompt from ‘Instant Support’ to ‘Lead Capture & Scheduling’ mode.

With n8n, we can create a workflow that checks the current day and adjusts the AI Agent’s behavior accordingly. This way, we can capture leads and schedule appointments on weekends, when our competitors are closed.

Here’s a code snippet to get you started:

// Weekend Router workflow

{
  "name": "Weekend Router",
  "nodes": [
    {
      "parameters": {
        "date": "{new Date().getDay()}",
        "mode": "Lead Capture & Scheduling"
      },
      "type": "n8n-nodes-base.if",
      "name": "Weekend Check"
    },
    {
      "parameters": {
        "LLM System Prompt": "{{node["Weekend Check"].json["mode"]}}"
      },
      "type": "n8n-nodes-base.updateItem",
      "name": "Update LLM Prompt"
    }
  ],
  "next": {
    "node": "Update LLM Prompt"
  }
}

Feel free to customize and expand this workflow to suit your needs. With n8n and our WhatsApp AI Agent, you can create a comprehensive sales bot that runs 24/7.
