Imagine a life without a calendar is difficult. You plan things in advance, mark important dates for you, watch the course of time, knowing what month, year, week, day is now. Using the knowledge of astronomy, astrology, mathematics, the Maya people composed twenty calendars that painted the future for hundreds of years. Some of them were found and people were amazed at the accuracy of the predictions. The hero of the story The Sacred Calendar - Father Noel arrived in the town of Morelia, which is in Mexico. He learned that there is another Mayan calendar there. This prediction on the stone is dedicated to the gods, so the Vatican sent for him his man. You will help him to find the artifact.
