Dates are computed with the browser's built-in Intl.DateTimeFormat calendar data. Some systems (notably the Chinese and Hindu calendars) have limited support in certain browsers and are labelled approximate. Day-of-year progress is derived by locating each calendar's own year boundaries, so leap months and variable year lengths are handled automatically.
