how to find public day in shamsi calendar?

Question

I'm looking for a way to find a holiday in the Shamsi calendar, I tried many ways. But in the end, I came to the conclusion that I had to enter the information manually

Another way I tried was to use moment Library (Persian and Jalali edition - ساعت ایران ) And this is my code :

var moment = require('moment-jalaali')
moment().format('jYYYY/jM/jD')

But I couldn't get results that way either

Do you think there is a way other than entering manual information?

Answer 1

One way is to use data insertion manually , and other way is using Ready databases

such as Jdf website ( I've used it before ، it's very usefull )
