gggg not working correctly

[maxsimych]

Describe the bug
gggg not returns week year, but just a year
The same functionality in moment js works correctly

const dayjs = require('dayjs');
const moment = require('moment')
const weekOfYear = require('dayjs/plugin/weekOfYear');
const weekYear = require('dayjs/plugin/weekYear');
const advancedFormat = require('dayjs/plugin/advancedFormat');
require('dayjs/locale/en-gb')
dayjs.locale('en-gb')

dayjs.extend(weekYear)
dayjs.extend(weekOfYear)
dayjs.extend(advancedFormat)
console.log(dayjs().toString())
console.log(dayjs().format('gggg-ww'))
console.log(moment().locale('en-gb').format('gggg-ww'))

2020-53
2020-53

Result
Sun, 03 Jan 2021 20:38:27 GMT

Sorry for the wrong reply above.

gggg should return the Week Year in Day.js the same as moment.js.

I've tested ok on my side, https://runkit.com/embed/9x7snt5xa0ts

It's ok in your case, because the issue appears only 1-3rd of January.

Here we can see wrong result for 2nd of January
