B2 = 0 × 7,200 = 0
A2 = 11 × 360 = 3,960
B1 = 13 × 20 = 260
B1 = 3 × 1 = 3

Applying rules 1, 2, and 3 (pp. [139], [140], and [141], respectively) to this number, the terminal date reached will be 10 Ahau 8 Chen, which is nowhere recorded in the text (see fig. [79], A).

The Initial Series corresponding to this date, however, may be calculated from the Initial Series which we have assigned to the date 12 Caban 5 Kayab:

9.14.13. 4.17 12 Caban 5 Kayab
0.11.13. 3
9.15. 5. 0. 0 10 Ahau 8 Chen

Although the date 9.15.5.0.0 10 Ahau 8 Chen is not actually recorded at Quirigua, it is reached on another monument by calculation just as here. It has a peculiar fitness here on Stela J in that it is just one katun earlier than the Initial Series on this monument (see fig. [78]), 9.16.5.0.0 8 Ahau 8 Zotz.

The other Secondary Series on this monument (see fig. [79], B) appears at B1-A2, and records 18 tuns, 3 uinals, and 14 kins, which we may write thus: 18.3.14. As in the preceding case, the date following this number in B2-A3 is its starting point, not its terminal date, a very unusual feature, as has been explained. This date is 6 Cimi 4 Tzec—compare B2 with the sign for Cimi in figure [16], h, i, and A3 with the sign for Tzec in figure [19], g, h—and as far as Stela J is concerned it is not fixed in the Long Count. However, elsewhere at Quirigua this date is recorded in a Secondary Series, which is referred back to an Initial Series, and from this passage its corresponding Initial Series is found to be 9.15.6.14.6 6 Cimi 4 Tzec. Reducing the number recorded in B1-A2, 18.3.14, to units of the first order, we have:

A2 = 18 × 360 = 6,480
B2 = 3 × 20 = 60
B2 = 14 × 1 = 14

Applying rules 1, 2, and 3 (pp. [139], [140], and [141], respectively) to the number, the terminal date reached will be 8 Ahau 8 Zotz, which does not appear in figure [79], B. The Initial Series corresponding to this date may be calculated as follows:

9.15. 6.14. 6 6 Cimi 4 Tzec
18. 3.14
9.16. 5. 0. 0 8 Ahau 8 Zotz
