How to change Gregorian date to Persian date in JavaScript?

Question

Can anyone help me to change Gregorian date to Persian in JavaScript? I want to use it in HTML and JavaScript.

Answer 1

To get it in Persian digits:

new Date().toLocaleDateString('fa-IR');
// ۱۳۹۹/۱/۲۳

To get it in Latin digits:

new Date().toLocaleDateString('fa-IR').replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
// 1399/1/23
