Perplexity

Check international holidays in Claude Desktop

Stop guessing which days banks are closed in foreign markets. Use `get_holidays` to pull specific public, bank, and religious dates for any country and year directly into your chat. Your AI client processes these dates instantly. You get precise schedules for project planning or travel logistics without leaving the app.

Verify regional coverage

Need to know if a specific country is included in the database? Run `list_supported_countries` to see exactly what regions this MCP server covers. This keeps your queries accurate. You avoid errors by checking the supported list before you try to fetch holiday data for obscure locations.

Automate scheduling with your MCP Server

Claude Desktop runs this MCP Server as a local subprocess for fast, reliable data retrieval. It bridges the gap between static text and live international calendars. Everything stays inside your local environment. You define the country and year, and the agent handles the rest of the heavy lifting.
