# How to Calculate Business Hours Overlap with Copilot

Copilot handles timezone conversions as structured data operations directly in your IDE, outputting results as markdown tables for team wikis, JSON objects for scheduling APIs, or iCal-compatible timestamp formats for calendar integration. Build DST-aware scheduling features, generate timezone comparison utilities, and integrate precise IANA timezone data into your applications without leaving your coding environment or importing heavyweight date libraries.

## Setup

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

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Get timezone info for America/New_York and Asia/Tokyo"
3. Copilot returns UTC offsets and DST details
4. Calculate the overlap programmatically from the data

## Example Prompt

```
Get timezone info for America/Chicago and Europe/London. Calculate 9-5 business hours overlap as JSON.
```

## Tips

- Build overlap calculators into team management dashboards
- Use timezone_info DST data for year-round accuracy
