Overview

Dates outside the range Remind can represent.

Remind counts days from BASE, which is 1990, and represents YR_RANGE years, which is 4000 (src/custom.h.in). So 1990-01-01 to 5990-12-31 is not a policy, it is the type. A date below the floor cannot be stored at all.

Three of the book's rules asked for a slice of this each -- TriggerComponentRange, DateConstantBeforeEpoch, DateOutsideRepresentableRange -- and Appendix B's own note suggested collecting them. One rule keeps the message identical wherever the date was written.

Two shapes are checked: a spelled-out date in a trigger, and a single-quoted date constant in an expression. A day of 32 or a month nobody has is caught by the same walk.
