Plenty. Search "Mayan Calendar Cortez" in your favorite search engine. I use Bing.
One result on the first page says:
The calendar was also prophetic. In the 8th century A.D. it predicted that white skinned bearded gods would arrive from across the sea on March 5th, 1519. On that precise date Cortez and his conquistadors arrived in the new world.That seems reasonably unambiguous to me.
The first Spanish arrived in the Yucatan peninsula (land of the Maya where the calendar was perfected) in 1511 as the result of a shipwreck. Cordoba sailed there deliberately in 1517. Cortez didn’t arrive in what is now Veracruz, central Mexico, among Aztec vassals, until 1519. This is not to denigrate his accomplishments, but he was not the first Bearded God to arrive in Mexico, by a long shot. Really the conquest of Mexico is more ambiguous that many acknowledge.
