Setting the date in date field sets it with one day before [duplicate]

It's the timezone difference read this.

Apparently when using new Date() you use the current time zone and valueAsDate takes a GMT dateTime

Changing you code to something like this

console.log(myInput.valueAsDate = new Date(1995, 0, 1,12));

should work

Update 1

console.log(myInput.valueAsDate = new Date(Date.UTC(1995, 0, 1));

Should work on all timezones.
