Holidays have a way of bringing people to together, whether they be family, friends, or even strangers from diverse social, political, and religious backgrounds. There's something about religious, cultural, and national celebrations that help us find common ground with one another. Many business owners and employees like to plan their vacations and PTO around holidays so they can maximize their planned time off. Others are just looking for a reference so they know when to expect closures of banks, post offices, schools, and various government agencies or services. There are currently eleven U.S. federal holidays. A holiday that falls on a weekend is usually observed on the closest weekday.
