One extended finger answers one hour. The thumb shown is an illustrative choice.
La Trappe hour signals · 1824 witness
A documented La Trappe rule answers the time by showing one finger for each hour, with parts of a finger for half and quarter hours.

Five fingers on one hand and two on the other answer seven hours.
One extended finger represents one hour.
Show 5 fingers on one hand: 5 hours.
Show 2 more on the other hand: 5 + 2 = 7 hours.

5 + 2 = 7 hours
La Trappe’s 1824 vocabulary specifies finger totals, not which fingers or hand to use. Half a finger means half an hour; a joint means a quarter-hour.

Existing public-domain engravings illustrate the documented finger totals and counting action. The artwork is illustrative and comes from separate sources; it is not a historical depiction of Cistercian practice. Brackets on the fractional examples are modern teaching annotations.
In the La Trappe time signal, show as many fingers as the number of hours. The converter illustrates 1–10 using the thumb-first sequence in the sourced engraving, with a second hand after five. Du Bois does not prescribe which fingers or hand to choose. His entry also specifies half of a finger for a half-hour and one joint for a quarter-hour. These fractional time signals are described in the dictionary.
One extended finger answers one hour. The thumb shown is an illustrative choice.
Four extended fingers answer four hours; finger selection follows the illustrative engraving.
Five fingers on one hand and two on the other answer seven hours.
Both open hands display ten fingers in total, answering ten hours.
This converter implements the documented hour-counting rule only for 1–10. It does not claim a universal medieval Cistercian cardinal-number code or invent a rule for 11 and 12. Existing public-domain engravings illustrate the finger totals. They come from a 1911 number-sign plate and a separate counting illustration, not Cistercian sources; finger selection and palm orientation remain illustrative. Loccum COUNT and HALF are separately dated vocabulary items, not arbitrary cardinal numerals.
Louis Du Bois printed a vocabulary of La Trappe signs in 1824, attributing its renewal to the Trappist reform of de Rancé. Its entry Heure describes numerical replies about time. This dated Cistercian Strict Observance witness is used here, without assigning its exact gestures to the medieval order as a whole. Earlier Loccum lists, printed by Leibniz in 1717, independently document COUNT and HALF.
