Pocket Digital Sundial For Prayer.
Ever wanted to pray like King David or how about the Apostles of the Holy Bible and Jesus Christ Himself who stated "are there not 12 Hours in a day?" and he went up to the Synagogue at the Hour of Prayer.
Byzantine Time originates even before the Byzantine Empire found among Ancient Judeans. It uses Unequal Hours like a Sundial. The next day begins at Evening rather than midnight on modern clocks. This Application Requires GPS to operate , how ever you can manually type in the Longitude and Latitude in the settings.
Byzantine Time is still kept by Holy Monks on Mount Athos, and the Eastern Orthodox Church keeps the Prayer Hours to this day.
