在没有浏览器进行与时区相关的任何调整的情况下，在 JavaScript 中写入日期的正确方法是什么

Question

I'm not in the GMT timezone and new Date('1995-02-22') gives me

new Date('1995-02-22') <-- Enter this in the console


Tue Feb 21 1995 16:00:00 GMT-0800 (Pacific Standard Time)

I'm coding something related to a birthday, so the year month and day are super important, but the time isn't. What is the proper way to handle this? Using moment.js seems beyond overkill.

Choose one: either create a Date with the correct date in UTC time, or with the correct date in the local timezone. If the timestamp might be used by other clients too, use UTC time for easy compatibility.

If you create the Date with the correct UTC time, then just use the get* UTC methods to retrieve the year/month/day.

 const date = new Date('1995-02-22'); console.log( date.getUTCFullYear(), (date.getUTCMonth() + 1), // 0 indexed date.getUTCDate(), );

Or create the Date in local time and use the local versions of the above, like .getFullYear .
