Depends on the company. The US maintains no requirements, federal holidays are a suggestion, not a mandate. A few states inside the US upgrade federal holidays to state holidays to required paid time off. Most don't. In the US paid holidays are a corporate "tradition" more than a regulated common good. Even US federal employee holidays vary between agencies and branches of government.
