HoursEnum: Index<24>

Represents the hours in a day using 24-hour format. A union of integer literals from 0 (midnight) to 23 (11 PM).

Uses the international standard 24-hour time format where:

0 represents midnight (00:00)
12 represents noon (12:00)
23 represents 11 PM (23:00)

Example

const formatHour = (hour: HoursEnum): string =>
  hour.toString().padStart(2, '0');

const is12HourFormat = (hour: HoursEnum): string => {
  if (hour === 0) return '12 AM';
  if (hour === 12) return '12 PM';
  if (hour < 12) return `${hour} AM`;
  return `${hour - 12} PM`;
};

const midnight = 0 satisfies HoursEnum;
const noon = 12 satisfies HoursEnum;
const elevenPM = 23 satisfies HoursEnum;
