moment('1402-01-02', 'jYYYY-jMM-JDD').format('jYYYY-jMM-jDD') return 1402-01-01

I don't know what the problem is, but there is an issue with the first and second days of any year.

if you add(1, 'day') to the first day of the year, it returns the same day again. you do it two times, and then it returns the second day of the year.

and also moment('1402-01-02', 'jYYYY-jMM-JDD').format('jYYYY-jMM-jDD') return 1402-01-01.

I think it's pretty self explainatory. plz help. tnx.
