Timetable Inca, Division of day
The day was divided as follows: dawn, full morning, midday, sunset, dusk, the night and midnight.
The Incas knew the solstices and equinoxes to perfection, dates were celebrated with great rituals of adoration and worship. Therefore the Incas determined two seasons:
- The dry season – Ch’akiy.
- The rainy season – Poqoy.
Usually, the observatories are located in their temples, but could also be found observatories on the tops of some mountains like Huayna Picchu. It is known that the "Incas astronomers", lived close to the tops of the mountains, which were dedicated full time to observing the behavior of the stars, also they used the reflection of water (water mirrors), and the projection of light and shadow, in sundials as the Intihuatana, being able to determine very accurately, the dates of the solstices and equinoxes.
The Incas had many holidays, which were also considered as days of rest; which usually they were linked to agriculture. Some of these celebrations were held on fixed days, but others were determined by the highest authority of the empire, the Inca.
The celebrations were popular ceremonies with music and song, which could last from three to seven days. Some of the Inca festivals still celebrated today in the city of Cusco, one of the most famous and popular, is the Inti Raymi – Sun Festival, which coincides with the winter solstice (June 21) and the celebrations for the anniversary of the city of Cusco. Another of the Inca festivals still celebrated in some provinces of the department of Cusco, is the Qhapaq Raymi, which coincides with the summer solstice (December 22).
