While speaking of Katun endings, this quick way to determine its Ahaw
coefficient may be useful.

To find the Ahaw date associated with a Katun ending date:

   - *Multiple Baktuns by -1 and Katuns by -2.*
   - *Sum Products and then add 4*
   - *Add sufficient 13's to make answer positiv*e.


Example: Find Katun edding for 9.5.0.0.0

(-1 x 9) + (-2 x 5) + 4 = -15
-15 + 26 (two 13's are sufficient -19 positive) = 11

Therefore 9.5.0.0.0 is 11 Ahaw
