# How to Convert Event Times with Claude

Claude approaches timezone conversion as a reasoning problem, analyzing UTC offsets, daylight saving transitions, and business hour constraints across multiple regions simultaneously to find solutions that actually work for everyone involved. It evaluates trade-offs when perfect overlap is impossible, flags edge cases like upcoming DST transitions that will shift your meeting times, and explains clearly why a particular slot works or falls outside reasonable hours for specific participants.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Convert our webinar at 2pm EST to all major timezones"
3. Claude returns the time in each attendee timezone
4. Ask: "Format this as a timezone table for our event page"

## Example Prompt

```
Our conference keynote is at 10am PST on April 5. Convert to EST, GMT, CET, IST, JST, and AEST. Format as a table for the event page.
```

## Tips

- Include UTC offset next to each timezone for absolute clarity
- Ask Claude to flag any timezone where the event falls outside business hours
