TypeError: dayjs(...).tz is not a function

Question

I am getting this error.

TypeError: dayjs(...).tz is not a function

My code is

const dayjs = require('dayjs');

const dayjsAmerica = dayjs("2014-06-01 12:00").tz("America/New_York");

Answer 1

Fix

Make sure you installed dayjs

npm install dayjs

const dayjs = require('dayjs');

const utc = require('dayjs/plugin/utc');

const timezone = require('dayjs/plugin/timezone');

dayjs.extend(utc); dayjs.extend(timezone);

Refer doc https://day.js.org/docs/en/timezone/timezone

Answer 2

this worked also for me as @kandula

npm install dayjs

const dayjs = require('dayjs');

const utc = require('dayjs/plugin/utc');

const timezone = require('dayjs/plugin/timezone');

dayjs.extend(utc); dayjs.extend(timezone);
