The two Mesoamerican cultures that relied heavily on calendar systems were the Maya and the Aztec civilizations. The Maya developed a complex calendar system that included the Tzolk'in (a 260-day ritual calendar) and the Haab' (a 365-day solar calendar), which were used for agricultural, religious, and ceremonial purposes. The Aztecs also had a similar system, utilizing the Tonalpohualli (a 260-day calendar) alongside the Xiuhpohualli (a 365-day calendar), integrating these calendars into their societal and religious practices. Both cultures demonstrated remarkable astronomical knowledge through their calendar systems.
The calendar system developed by the Olmec civilization was adopted by most early Mexican cultures. This calendar, known as the Mesoamerican Long Count calendar, played a significant role in the civilizations that followed, such as the Maya and Aztec.
The Maya calendar was developed by the ancient Maya civilization in Mesoamerica. It was likely influenced by earlier Mesoamerican cultures and their understanding of astronomy. The Maya's advanced knowledge of mathematics and astronomy allowed them to create a complex calendar system that accurately tracked time and celestial events.

The Maya civilization in Mesoamerica had a complicated calendar system that incorporated cycles of the sun, moon, and Venus. They developed a detailed calendar known as the Mesoamerican Long Count calendar which accurately tracked time over long periods and highlighted their understanding of astronomical cycles.
Lunar calendar is an old system to record time. Canada is a modern country with a blend of all sorts of cultures. So it is much more preferable not to use the lunar calendar as this could lead to different system of recording time.
The Maya developed a sophisticated calendar system called the Mesoamerican Long Count calendar to track the movements of celestial bodies. This calendar allowed them to accurately predict astronomical events such as eclipses. They also built impressive observatories to monitor the movements of the sun, moon, stars, and planets.
Flourished prior to European contact
Early civilizations used the solar portion of the 52 year calendar for planning farming seasons.
They were obessed with finding out what would happen to them in the future (2012) and they were, as the ancient greeks and romans were; obessed with history and keeping records, diaries etc.
A calendario span, also known as a calendar round, is a cycle of 52 years in the Mesoamerican calendar system where two separate calendar systems— the Tzolk'in and the Haab— align to repeat the same combination of dates. This cycle was used by civilizations like the Maya and Aztec to track the passage of time.
Properly speaking, there is no "English" calendar system. You probably mean the predominant Western Calendar (also called the Christian Calendar). This calendar system is best called the "Gregorian Calendar", after Pope Gregory XIII who introduced the calendar system in 1582.
