## Description

Calendarios Nacionales is a free online reference for public holidays, work schedules, and important dates across Spain, Argentina, Colombia, Mexico, and the United States. It organizes national, regional, and local holidays, with coverage down to municipalities in Spain and corresponding regional areas in the other countries. Visitors can explore bridge-day opportunities, school calendars, official tax deadlines, and a calculator for working days between two dates. The site also provides calendars for lunar phases, eclipses, astronomical events, religious observances, and international commemorations.

Calendarios Nacionales draws on public and government sources, including the BOE, AEAT, AFIP, DIAN, SAT, IRS, and other relevant agencies. Its information is processed and automatically checked, with daily updates stated on the site; users are advised to confirm details with the official source before making legal or employment decisions. Calendar data can be exported in formats such as ICS, CSV, XLS, and PDF where available. A free public JSON API is offered without an access key or usage limits. The service requires no registration.
