The Mayan calendar dates back to around 3114 BCE. It was a complex system that included various calendar counts, such as the Tzolk'in (260-day calendar) and the Haab' (365-day calendar), as well as the Long Count calendar used for historical dates.
The Mayan Long Count calendar started on the 11th of August, 3114 BC. The date 3372 BC predates the start of the Long Count calendar by about 240 years. Therefore, there are no specific facts about the first day of the Mayan calendar in 3372 BC.
It was just another calendar system, as arbitrary as our own. It was also a 365-day calendar, but instead of 30/31-day months, it had eighteen 20-day months, plus another 5-day month for festivities. Most probably, the 53 year "long cycle" corresponded to the sight of one or more comets.
A lunar calendar is a calendar based on the phases of the moon as opposed to one determined by the Sun, known as the solar calendar. The lunar calendar varies from different regions. For example, the Hindu calendar starts their first day of the month on a different day than to the Chinese calendar.
It was a 365-day calendar similar to our present-day calendar.
The Mayan calendar is extremely complex and evolved over a long period of time - certainly no one person could have devised it.In fact the Maya priests copied the "ritual calendar" part of it from the Zapotecs, who had developed it earlier; to this the Mayas added the Long Count, the Solar Calendar and the Moon Calendar, weaving them intricately together like the cogs of a huge machine.The 260-day Ritual Calendar (tzolkin) on its own was a complex affair, consisting of 20 thirteen-day periods, each day named and numbered. Only every 52 years would the date correspond with the 360-day solar calendar. The ritual calendar is probably the most ancient calendar in Mesoamerica.Each part of the calendar operates in never-ending cycles; as each cycle is completed another begins - so if we think of the Gregorian calendar we use today as a "time line", the Maya calendar is an endless circle.ManYanSduH
It is a single day on a calendar with one date, starting from midnight to midnight. This would be different from things like a working day, which would not be 24 hours, or a 24 hour period starting on one day and finishing on the next day.
