Get Today's Date and Day Using n8n Function Node

This workflow demonstrates a basic yet essential utility in n8n: fetching the current date and day of the week via JavaScript in a Function node. It starts with a Manual Trigger node, which initiates execution on demand. The Function node then processes the input, creating an ISO timestamp with new Date().toISOString() and determining the weekday using getDay() mapped to an array of day names (Sunday to Saturday). The results are added as 'date_today' and 'day_today' properties to the output JSON item.

The benefits are straightforward: no external API calls or nodes required, making it lightweight, fast, and dependency-free. It's ideal for developers learning n8n's Function node capabilities or needing quick date utilities without added complexity. This approach teaches manual data manipulation and item processing, foundational for more advanced workflows.

Use cases include timestamping logs, personalizing customer emails with greetings like 'Happy Monday!', generating reports, or integrating into larger automations for scheduling and notifications. In e-commerce or customer service, it can enrich support tickets with current date/day info. Easily extensible by chaining nodes for emails, databases, or APIs.
