“A C++14 approach to dates and times"
summary
A compact C++14 date/time library (date.h, plus optional tz.h) implements single-header extensions to std::chrono: a serial daypoint time_point, lightweight field types (year/month/day, year/month/weekday, last), and constexpr algorithms so many conversions and epoch math happen at compile time. It allows constructing invalid dates and deferring handling (checkable with ok()), parses the IANA tz database including leap seconds, throws no exceptions, and beats heavy implementations in size and cold-cache speed (library object ≈15KB; competitor full app ≈132KB; hot/cold timings in the 100–300ns vs 89ns/3µs ranges).
