Day of Week (Locale Aware)

Gets or sets the day of the week according to the locale.

This requires the Weekday plugin to work

If the locale assigns Sunday as the first day of the week, dayjs().weekday(0) will be Sunday. If Monday is the first day of the week, dayjs().weekday(0) will be Monday.

dayjs.extend(weekday)

// when Sunday is the first day of the week
dayjs().weekday(-7); // last Sunday
dayjs().weekday(7); // next Sunday

// when Monday is the first day of the week
dayjs().weekday(-7) // last Monday
dayjs().weekday(7) // next Monday


// when Sunday is the first day of the week
dayjs().weekday(-5) // last Tuesday (5th day before Sunday)
dayjs().weekday(5) // next Friday (5th day after Sunday)
