Method utc()/format() incorrectly parses the date string 'ddd, MMM D YYYY'

[eugenkr]

Describe the bug
If your date string format is 'ddd, MMM D YYYY' than dayjs.utc() creates a wrong object, but if you change the format to 'YYYY-MM-DD' it works correctly. Probably it's format() issue. Example:

dayjs.utc('Fri, Jan 28 2025').format('YYYY-MM-DD') => '2025-01-27'
dayjs.utc('2025-01-28').format('YYYY-MM-DD') => '2025-01-28'

Expected behavior
This command dayjs.utc('Fri, Jan 28 2025').format('YYYY-MM-DD') have to result in 2025-01-28

I have the same problem when formatting a date to the Brazilian format; it's inverted. For example:

const originalDate = "2025-02-05";

// Formatting the date
console.log(dayjs(originalDate).utc().format("DD/MM/YYYY"));

// Output:
02/05/2025

// Expected:
05/02/2025
