Independence Day is a federal holiday. If July 4 is a Saturday, it is observed on Friday, July 3. If July 4 is a Sunday, it is observed on Monday, July 5. Government offices and schools are closed. Some businesses may be closed as well. In some years, many employees use a proportion of their vacation days to create a long weekend. This can cause congestion in some places, particularly towards popular holiday destinations.
There are many public events, parades, shows and fireworks displays. This may cause local disruption to traffic. Public transit systems do not usually operate on their regular timetables.
