Answer 1

You should read the fine manual

Note: parsing of date strings with the Date constructor (and Date.parse, they are equivalent) is strongly discouraged due to browser differences and inconsistencies.

You should probably go with new Date(2016, 3, 14) (3 because the month integer is zero-based). This will create a date in your timezone at midnight, April 14.

Answer 2

To get the UTC(GMT) time use .toUTCString() instead of the default .toString().

If you want to create local time midnight date from string, use iso8601 like 2016-04-01T00:00:00-07:00. Note the timezone offset.
