Compile-time grids

alias January2027 = StaticMonth!(2027, 1, WeekStart.monday);

The template evaluates the same month builder used by runtime grids. Its compile-time constants include 42-cell backing storage, active row/cell counts, weekday summaries, and previous/current/next-month and weekend masks. Natural mode keeps the fixed backing representation but marks only its natural cells as active.

Compile-time specialization is useful when those constants feed another template or static table. For changing dates, prefer the runtime API to avoid creating needless template instances.

StaticYear!2027 provides month lengths and starting weekdays without embedding twelve complete grids.
