Create a date object

By default, Date uses the browser’s time zone and display a date as a full text string: Tue Oct 27 2020 22:52:28 GMT-0600 (Mountain Daylight Time)

new Date()
new Date(year, month, day, hours, minutes, seconds, milliseconds)
new Date(milliseconds)
new Date(date string)

new Date() creates a new date object with the current date and time.

new Date(year, month, day, hours, minutes, seconds, milliseconds)

new Date(year, month, day, hours, minutes, seconds, milliseconds)
new Date(year, month, day, hours, minutes, seconds)
new Date(year, month, day, hours, minutes)
new Date(year, month, day, hours)
new Date(year, month, day)
new Date(year, month)
new Date(year)

Create UTC date

Use new Date(string) constructor. String must be in this format YYYY-MM-DDTHH:MM:SSZ. Note the T in the middle and Z at the end.

let date = new Date("2020-08-25T00:00:00Z")

UTC to local Date and Time

Use the toLocaleDateString() method and the toLocaleTimeString() method together. The method toLocaleDateString() returns a transformation of UTC date to local date in this format (month/day/year). The toLocaleTimeString() returns a transformation of UTC time to local time in this format hour:minute:second AM/PM (11:30:59 PM)

In many cases, API servers return dates in UTC and clients translate UTC dates to local dates.

new Date(data.createdAt).toLocaleDateString()+" "+new Date(data.createdAt).toLocaleTimeString()

data.createdAt and data.updatedAt are in this format YYYY-MM-DDTHH:MM:SSZ
