The Ronpet web app is a living implementation of the Ancient Egyptian Festival calendar presented in Tamara Siuda’s “The Ancient Egyptian Daybook”. It combines the ancient civil and lunar calendars into a fluid single year calendar. It enables easy conversion between our modern day Gregorian calendar and the ancient equivalent. This calendar is by default calibrated to the Kemetic Orthodox standard, but can be calibrated to any desired Wep Ronpet start date. You may register for a free account on the site to sync your settings across multiple browsers and devices. The web app works equally well on mobile, tablet, and desktop!

A selection of the most significant holidays throughout the year are available for free. Access to the complete database of 941 Civil festivals, 121 Lunar festivals, and 237 notes can be purchased for $9.99.
