The American calendar is filled with numerous holidays. The following table shows some of the more popular holidays. Important national holidays have been indicated in bold face. Most non-essential government offices will be closed on these days. (Fire, Ambulance and Police are always open.) Banks and post offices also tend to be closed on these days, and many businesses will give their employees the day off.

It is also important to be aware of the holidays of people of other religious faiths. For example, important Jewish holidays include Yom Kippur, Rosh Hashanah, Sukkoth, Chanukah, and Passover. Yom Kippur, Rosh Hashanah, and Sukkoth occur in the fall. Chanukah occurs in December, near Christmas. Passover occurs in March or April, near Easter.
