"The Maya were remarkable mathematicians and astrologers, and certainly some of history's most proficient, accurate keepers of time. To appreciate the Maya concept of time, it is important to understand the different[ie. more than one] calendar systems they developed and how they were used." ...
"The 'Tzolk'in' or 'Sacred Round' calendar consists of a 260 day cycle." ... "It is useful to think of the Tzolk’in as two intermeshing gears, one inside the other, with the 13 numerals marked at intervals around the smaller gear set inside a larger one that is marked with day names denoted by glyphs." ...
"The 'Haab' calendar is based on the cycle of the sun and was used for civil, agricultural, accounting and administrative purposes." ...
"To measure, record and predict events over longer periods of time, the Mesoamericans developed the 'Long Count'. Long Count dates are the ones usually recorded on monuments and stellae." ...
"It is widely accepted that the Long Count's "zero”, or creation date was August 11 3114BC, and that this marked the end of a previous world and the beginning of the current one, and it is further conjectured that the end of this current thirteenth b'ak'tun will fall on the Maya date 184.108.40.206.0, or December 21 2012." ... "This event has been given much attention in recent times and unfortunately has been subject to gross misinterpretations of Maya history and cosmology. Sensational films, television shows, internet exposure and other media present the end of the 13th b'ak'tun as “proof” of an impending apocalypse and global destruction. In fact, most serious Maya scholars and contemporary Maya daykeepers and other accepted spiritual and village leaders consider it to be simply the end of one cycle of time and the beginning of another." .
People are welcome to use these blog posts for research purposes. However, I certainly don't write them to make things easier for students (and others) who are often tempted to 'copy and paste' original writing, and present it as their own writing. In most cases it needs to be re-written in their words, and I would expect an entry in the references of the document - as is normal practice. If they include quotes (in quotation marks) please ensure that there is a reference to the original author.

By the way, don't believe anybody who says that di-hydrogen monoxide is toxic. 'Di' means two, and 'monoxide' means one oxide. So, H2 and O ... H2O (water).

"Created by Cuffy and Clow in 1997, and based on Greenland ice core records, this chart shows global temperatures for the past 15,000 years."
"Temperatures have been warmer than today for almost all of the past 10,000 years."
“ 'Natural global warming much more intense than modern warming has occurred many times in the geologic past without CO2 change,' said Easterbrook."
