Day Atl (Water) is governed by Xiuhtecuhtli, God of Fire, as its provider of tonalli (Shadow Soul) life energy. Atl is a day for purification by subjecting oneself to the ordeal of conflict. It is a good day for battle, a bad day for rest. Water brings out the scorpion, who must sting its enemies or else sting itself. Atl is the day of the holy war, which is always a battle with one's own enemies within.
Some people that were born on day Atl and have their life energy provided by Xiuhtecuhtli are Madonna, Robbie Williams, Julia Roberts, Jennifer Lopez, Christina Aguilera, Terrence Howard, Beyonce Knowles, Mick Jagger.
