(Spoiler: the Mayans didn't say it'd be tomorrow.)

"The Mayans believed at at the conclusion of each pictun cycle of about 7,885 years the universe is destroyed and re-created. Those with apocalyptic inclinations will be relieved to observe that the present cycle will not end until Columbus Day, October 12, 4772 in the Gregorian calendar. Speaking of apocalyptic events, it's amusing to observe that the longest of the cycles in the Mayan calendar, alautun, about 63 million years, is comparable to the 65 million years since the impact which brought down the curtain on the dinosaurs -- an impact which occurred near the Yucatan peninsula where, almost an alautun later, the Mayan civilisation flourished." -- from Fourmilab's calendar converter

"Mayan inscriptions occasionally mention predicted future events or commemorations that would occur on dates far beyond the completion of the 13th b'ak'tun. Most of these are in the form of 'distance dates'; Long Count dates together with an additional number, known as a Distance Number, which when added to them makes a future date. On the west panel at the Temple of Inscriptions in Palenque, a section of text projects forward to the 80th 52-year Calendar Round from the coronation of the ruler K'inich Janaab' Pakal. Pakal's accession occurred on 9.9.2.4.8, equivalent to 27 July 615 AD in the proleptic Gregorian calendar. The inscription begins with Pakal's birthdate of 9.8.9.13.0 (24 March, 603 AD Gregorian) and then adds the Distance Number 10.11.10.5.8 to it, arriving at a date of 21 October 4772 AD, more than 4,000 years after Pakal's time." -- from Wikipedia
