The normal Aztec calendar was based on the solar year and was xihuitl (at the Mayan haab). It had 18 months that comprised of 20 days each, plus 5 additional days to include misfortune fully (unlucky days). Each month had four weeks and 5 days each. The last day of the week was public market day (tianquiztli) and also rest day. There were a total of 288 working days and 72 tianquiztli year. During the 5 unlucky days you should not work. This yielded a total of 365 days. But as a year is about 6 hours longer, an excess resulted in days. Therefore, after each 52 years 12 ½ switching days was inserted. A more accurate approximation of the solar year was achieved in the European calendar.
