# Local Dates vs UTC Dates
As you are no doubt aware, all dates in JavaScript are held as an object which contains a number that represents the number of milliseconds since midnight of 1st January 1970 UTC.
By default, when you select a date, the datepicker emits a local date i.e. a JavaScript object that represents the date at midnight in the browser's local timezone. So, for example, depending on whether you're on daylight saving time, if you're in central Europe, this may be one or two hours before UTC and if you're in New York, this may be four or five hours after UTC.
NOTE
If you want the datepicker to emit a UTC date, you may set the use-utc prop to true:
<Datepicker :use-utc="true" />
# Be consistent
If you are using local dates, be sure that any dates you input into the datepicker
via the value, open-date, disabled-dates, or highlighted props are also local dates. Likewise, if you are using UTC
dates, be sure to enter these values as UTC dates.
# Local dates
One way to create a local date in JavaScript is to use the
new Date(year, monthIndex, day) format:
<Datepicker :value="new Date(2000, 0, 1)" />
# UTC dates
To create a UTC date, you may use the new Date('yyyy-mm-dd') format:
<Datepicker :value="new Date('2000-01-01')" />
