They don't have leap years because they don't need them. The last day of the old year is also the first day of the new year and each year starts in a different hour so is way more precise than our current calendars.
Leap years were first implemented in the Gregorian calendar in 1582.
The Aztec calendar is made up of two interlocking cycles, the 260-day Sacred Calendar and the 365-day Solar Calendar, creating a 52-year calendar round. This is different from our Gregorian calendar, which is a 365-day solar calendar with a leap year every four years. Additionally, the Aztec calendar was based on a combination of astronomical observations, religious beliefs, and mathematical calculations.
No, odd-numbered years are never leap years in either the Gregorian calendar or the Julian calendar.

Yes if your calculations are correct taking into account of leap years otherwise no. 1993 and 2015 do not share the same calendar. It is not always the case that years repeat every 11 years.
Julius Caesar introduced leap years when he reformed the Roman calendar in 46 BCE. His calendar, which is called the Julian calendar, was in use for almost 20 centuries. Beginning in 1582, it was eventually replaced by the Gregorian calendar, which is almost identical to the Julian calendar but is more accurate because it has fewer leap years.

2012 is a leap year. Leap years fall once every four years to keep our calendar years in sync with the seasons.
In the Gregorian calendar, No Only century years divisible by 400 are leap years.
Yes. Basically all multiples of 4 are leap years - with some exceptions when the year is also a multiple of 100.
every 4 years....2012 will be the next leap year.
The Julian calendar has more leap years. Every 400-year period of the Julian calendar is three days longer than the same period in the Gregorian calendar.
