dates – Macros for parsing date strings

This pack­age pro­vides a macro, \dateread, that can be used to parse date strings, ei­ther in­di­vid­u­ally or re­cur­sively. The macro ex­pects a hu­man-read­able syn­tax, which it con­verts into an in­te­ger (a “long date”) that can be more eas­ily used for some types of com­pu­ta­tion. A set of com­pan­ion macros and to­ken reg­is­ters is also pro­vided for con­vert­ing long dates into hu­man-read­able form.
