According to the documentation use .format('YYYY-MM-DD').

const formated = dayjs('1. 1. 2023').format('YYYY-MM-DD');
console.log(formated);
<script src="https://cdnjs.cloudflare.com/ajax/libs/dayjs/1.11.7/dayjs.min.js" integrity="sha512-hcV6DX35BKgiTiWYrJgPbu3FxS6CsCjKgmrsPRpUPkXWbvPiKxvSVSdhWX0yXcPctOI2FJ4WP6N1zH+17B/sAA==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

I think what you are looking for (if dayJS doesn't parse YYMMDD out of the box) is the following plugin: custom_parse_format.

First you add the plugin (see docs under "Plugins" how to load plugin for NodeJS or browser):

var customParseFormat = require('dayjs/plugin/customParseFormat')
dayjs.extend(customParseFormat)

Then you can parse a custom date format like YYMMDD:

dayjs(createdAtStart, 'YYMMDD').format('YYYY-MM-DD')

Of course, you can replace format with any other method or chain of methods.

const dateString1 = "20230209150300";
const pattern1 = /(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/;
const formatedDate1 = dateString1.replace(pattern1, '$1-$2-$3 $4:$5:$6');
