Pakpi Calendar is a versatile calendar application designed specifically for the Shan-speaking community, available for Android devices. It features two calendar types: the traditional 7-day global calendar and the unique 30-day Pakpi calendar, which is aligned with Shan cultural practices and lunar phases. This dual-calendar system allows users to easily switch between different modes and stay in tune with their cultural heritage.

In addition to calendar functionalities, Pakpi Calendar includes a note-taking feature that utilizes a local database for efficient storage. Users can save notes either for the current year or for all subsequent years, making it convenient for tracking important dates such as birthdays and anniversaries. The app also provides a holiday tracking feature, allowing users to view significant dates and navigate through different years effortlessly.
