Rules used to determine which day period to use (See dayPeriods below). The rules can either be an array or a single value. If it's an array, consider it as "from" and "to". If it's a single value then it means that the period is only valid at this exact value. There is always the same number of rules as the number of day periods, which means that the first rule is applied to the first day period and so on. You should fallback to AM/PM when there are no rules available.

Day Periods indicate roughly how the day is broken up in different languages (e.g. morning, noon, afternoon, midnight, ...). You should use the function getLocaleExtraDayPeriodRulesto determine which period to use. You should fallback to AM/PM when there are no day periods available.
