Page-a-Day is a historical calendar application, designed to give you an easy-to-use interface for keeping track of history events and public holidays.

It provides you with a rich database of information on a wide variety of events from ancient times to the present day, with an option to choose from various cultures. 

The app can alert you about holidays in your calendar or in the database, and it can display your current location, so you'll always be aware of when the event you are interested in is happening.

A built-in trivia quiz game allows you to test your knowledge of the era or your historical events. The app can alert you for upcoming events, such as special holiday events or observances. Additionally, Page-a-Day supports your device's calendars, so you can use your event database to display the events on the device's calendar.
