Provides real, official public holiday data for ~100 countries with tools to list holidays for a year and check if a specific date is a holiday. Free, no API key required, powered by Nager.Date.
Computed from public signals only — stars, package downloads and how many registries list it. It measures how established a project is, not whether it is safe or right for you.
