mdDatepicker: is one day off when typing

Bug

What is the expected behavior?

Date when typing should not be one day off

What is the current behavior?

So when I select a date via calendar pop-up and pick a day it gives me a correct day, but when I type a date - it gives me one day off, e.g. typing 2012-12-12 gives me Tue Dec 11 2012 00:00:00 GMT-0500 (EST)

CodePen and steps to reproduce the issue:

CodePen Demo which shows the issue: https://codepen.io/luninroman/pen/gzaPvR

Detailed Reproduction Steps:

Pick a date via input field, but not a calendar

Which versions of AngularJS, Material, OS, and browsers are affected?

AngularJS 1.6.9
Chrome 66.0.3359.117

Is there anything else we should know? Stack Traces, Screenshots, etc.

As you may see date is different from the one I typed
My current timezone Easter, not sure if it matters

I believe that this is the same general issue that is tracked in, even though ng-model-options is not used:

Looks like this occurs only if the $mdDateLocaleProvider.formatDate is set. If the config block is removed, everything works fine.

Can confirm this is actually not a bug.

What happened here is you overwrote $mdDateLocaleProvider.formatDate which tells angular material how to convert a date object into a string. You also need to overwrite the $mdDateLocaleProvider.parseDate functionality in order to tell angular material how to parse your date string back into a date object.

@codymikol thank you for looking into this! Your suggestion looks good.
