- [ ] Yes, this behavior used to work in the previous version
### The previous version in which this bug was not present was
_No response_
### Description
Typing a date in "YYYY-MM-DD" format will format the date to "M/D/YYYY" but a day behind. This occurs using the control in various modes, including the date range picker.
### Reproduction
Steps to reproduce (can use demo on documentation page):
1. Render date picker with default formatting.
2. Type in the value "2023-07-06"
3. Lose focus of the input field.
4. The date picker changes the value to: "7/5/2023"
### Expected Behavior
I expect to see the date represented in a different format with the same date value.
Value entered: 2023-07-06
Expected result: 7/6/2023
### Actual Behavior
The date in the proper format, but one day behind.
Value entered: 2023-07-06
Actual result: 7/5/2023
### Environment
This bug occurs on the demo page for angular material:
https://material.angular.io/components/datepicker/overview
- Angular: v14+
- CDK/Material: v14+ (probably earlier)
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Windows
Contributor guide
Research direction
Start with the Angular Material datepicker demo at material.angular.io and reproduce the YYYY-MM-DD input losing focus in the default and date-range modes. Trace the datepicker input parsing and formatting path, then verify that 2023-07-06 is displayed as 7/6/2023 rather than 7/5/2023 without changing the underlying date value.
