I first added -

npm install moment-timezone

Then this is the code I used.

import { GlobalConfiguration } from "../cfg"
import { ValidLocale } from "../i18n"
import { QuartzPluginData } from "../plugins/vfile"
import moment from "moment-timezone"
 
interface Props {
  date: Date
  locale?: ValidLocale
}
 
export type ValidDateType = keyof Required<QuartzPluginData>["dates"]
 
export function getDate(cfg: GlobalConfiguration, data: QuartzPluginData): Date | undefined {
  if (!cfg.defaultDateType) {
    throw new Error(
      `Field 'defaultDateType' was not set in the configuration object of quartz.config.ts. See https://quartz.jzhao.xyz/configuration#general-configuration for more details.`,
    )
  }
  return data.dates?.[cfg.defaultDateType]
}
 
export function formatDate(d: Date, locale: ValidLocale = "en-US"): string {
  return moment.tz(d, "Asia/Dhaka").format("MMMM Do, YYYY • h:mm a")
}
 
export function Date({ date, locale }: Props) {
  return <>{formatDate(date, locale)}</>
}
