Locale#calendar 应具有以下格式字符串。

¥Locale#calendar should have the following formatting strings.

This requires the UpdateLocale plugin to work

dayjs.extend(updateLocale)

dayjs.updateLocale('en', {
  calendar: {
    lastDay: '[Yesterday at] LT',
    sameDay: '[Today at] LT',
    nextDay: '[Tomorrow at] LT',
    lastWeek: '[last] dddd [at] LT',
    nextWeek: 'dddd [at] LT',
    sameElse: 'L'
  }
})

每个 Locale#calendar 键也可以是一个回调函数，其范围是当前 Day.js 对象，第一个参数是描述现在的 Day.js 对象。它应该返回一个格式化字符串。

¥Each of the Locale#calendar keys can also be a callback function with the scope of the current Day.js object and first argument a Day.js object that depicts now. It should return a formatting string.

function callback (now) {
    return '[hoy a la' + ((this.hour() !== 1) ? 's' : '') + ']' + now.format();
}
