# How to Plan Construction Schedules with ChatGPT

ChatGPT turns sunrise and sunset data into practical planning advice that goes beyond simple time lookups. It helps you build event timelines around golden hour, understand how seasonal daylight changes will affect travel to unfamiliar destinations, and schedule outdoor activities when the light will be at its best. ChatGPT explains the quality of light at different twilight phases, recommends the ideal time to arrive at a viewpoint, and builds complete itineraries around the natural rhythm of the sun.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Get daylight times for our site location this week"
3. ChatGPT returns sunrise and sunset data
4. Request: "Build a work schedule that maximizes daylight hours"

## Example Prompt

```
What are the daylight hours at our Portland construction site this month? Help me plan crew schedules.
```

## Tips

- ChatGPT can build full weekly schedules with start and stop times
- Ask for seasonal projections to plan ahead for winter hour reductions
- Factor in break times relative to the midday sun
