Working overlays
Overlay faces of the product
These are the strongest public overlay pages right now. They open with today’s information by default and are meant to be the user-facing homes of those systems, not just metadata explainers.
Use these pages when the main question is not “what is the bare converted date?” but “what does this day mean in this overlay?” That includes feasts, fasts, prayer or halachic times, liturgical cycles, and Soviet reform-phase context.
