São José dos Campos celebrates the feast of its patron saint on March 19, resulting in changes to public service operations during the holiday. According to the municipal government, essential services such as urban mobility, security, and healthcare will remain fully operational, with hospitals and emergency units providing continuous care throughout the holiday.

However, several municipal departments will be temporarily closed, including the Municipal Office, Basic Health Units, and Family Health Units, all of which are set to reopen on Monday, March 23. This means that certain services will not be available during the holiday, but the public can rely on critical health and safety services being functional. Additionally, regular waste collection and outdoor market operations will remain unaffected through the holiday period.

For specific services like voluntary delivery posts, customer service lines, and the local market, hours will be modified on the designated days. For instance, voluntary delivery points will operate only from 8 AM to noon on March 19, indicating a well-coordinated approach by local authorities to balance celebrating the holiday while ensuring essential services are still accessible for the community.
