Of course they are. Pretty much every Mesoamerican site has astronomical alignment and sight lines.
This mountain was so important in pre-Hispanic life that, according to historical records, the lords of Texcoco, Tenochtitlán and Tlacopan (who were part of the Triple Alliance) attended. In the form of pilgrimage and after long walks, they reached the top to leave offerings and sacrifices to ask for rain to the god Tlaloc.

Since those aren’t, AFAIK, significant solar calendar dates, not agricultural dates, what does the alignment signify? I know the article says that is the beginning of their year, but WHY? What is special about that date?
Since any straight line pointing to anywhere in the ESE-SSE or WSW-SSW will ‘align’ with the same sunrise or sunset dates twice a year, which came first: the alignment causeway, or the calendar?
