Bug confirmed.

Current workaround

var dayjs = require("dayjs")
var advancedFormat = require('dayjs/plugin/advancedFormat')
var weekOfYear = require('dayjs/plugin/weekOfYear')

dayjs.extend(advancedFormat)
dayjs.extend(weekOfYear)


dayjs().format('YYYY年第wo周')

@iamkun hello, i also find dayjs().format('gggg')not working, but momentjs support it. expect dayjs support it

[iamkun]

@sam019

'gggg' is already supported in advancedFormat plugin (and depend on weekYear plugin)

dayjs.extend(weekYear)
dayjs.extend(advancedFormat)

dayjs().format('gggg')
