Mexico does not celebrate "Presidents' Day." That is a U.S. federal holiday (third Monday in February).
However, Mexico has a major patriotic holiday in early February:
This is a mandatory federal holiday (día festivo oficial) with closures of banks, government offices, and schools. It honors the progressive 1917 Constitution (land reform, labor rights, secular education).
Other February dates: Feb 24 – Flag Day (Día de la Bandera) (civic, not a day off). Feb 19 – Army Day (Día del Ejército) (military observance).
So if it's mid-February, it's not Presidents' Day in Mexico—it's likely a regular work week unless it's the Constitution Day long weekend.
