How the Ruleta Selectora de Fechas y Calendario Settles random values and utility picks
The Ruleta Selectora de Fechas y Calendario exists for one specific failure mode: needing an unbiased value fast without opening a spreadsheet. It loads with 10 ready-made entries (Hoy, Mañana, Este Viernes, Este Sábado, and more) so you can spin within a couple of seconds, then swap in your own list when the defaults do not match your situation.
What you get out of it is a reproducible, shareable generator instead of an ad-hoc guess. The stopping angle comes from window.crypto.getRandomValues() rather than Math.random(), and each slice occupies an arc exactly proportional to its weight — so the visual you see on the canvas is a literal picture of the odds.

Recommended setup: Quick 2.5-second spin; weighting off unless you need skewed odds.
