With C++20, the std::chrono library received a major update, introducing (among other things) support for representing dates. An abstract (not necessarily valid) date can be represented using the std::chrono::year_month_day type, which supports arithmetic operations for years and months. An abstract date can be normalized to a system time, which also supports day arithmetic operations. System time truncated to second precision conceptually represents a date + time (std::chrono::sys_seconds), and truncated to day precision represents a date only (std::chrono::sys_days). Finally, std::chrono::weekday can be constructed from a system time to obtain the weekday.

1yWould be great to see more on conversions between clocks and time zones! I recently discovered that the system time zone database on Windows is pretty much hopelessly flawed and the time-zone support on clang is still quite limited!
