Holidays and Observances

This guide provides information about diverse cultural celebrations and religious holidays. It includes calendars and brief descriptions of the events. This resource can assist in event planning and classroom activities.

Holidays and accommodations

As a worldwide institution, Webster University emphasizes diversity and global citizenship. When planning activities, faculty, staff, and students can access this guide for dates of religious holidays and cultural events, as well as to learn about dietary restrictions and recommended accommodations.

The main calendar is arranged by the U.S. academic year (June through May) for the current and next school year. Some holidays are based on the lunar calendar—which can vary based on region and practice—and, therefore, vary from year to year.

Notes on dietary restrictions

Kosher restrictions apply
Jewish dietary guidelines which apply daily throughout the year. These restrictions include pork, shellfish (fish is allowed) and mixing meat with dairy.


Halal restrictions apply
Islamic dietary laws which apply throughout the year. These restrictions include alcohol and pork.


  • Occasional dietary restrictions for additional religions are listed with the specific event to which they apply.

Great care has been given to assure accuracy of the dates. However, sources often differ on dates and on the spelling of the holiday. Please let us know if there are any obvious errors. Also, please let us know if there are any other dates that we should consider including.
