5 toolsauthHTTPregistry active
Summary
Connects Claude to Inday's public holiday API covering 30+ countries. You get straightforward queries for checking whether a date is a holiday, counting working days between dates, and pulling full calendar data by country and year. Reach for this when you're building scheduling tools, calculating business day intervals, or need to validate dates against regional holidays in user-facing apps. The streamable HTTP transport means you can run it remotely without local setup. Saves you from maintaining your own holiday dataset or wrestling with inconsistent regional calendar rules across different markets.
