Changing the Calendar date in BIOS does not work

In today’s publication, we will identify the cause and then provide a possible solution to the problem of why the calendar date changes in BIOS are not reflected in Windows 10. The BIOS (Basic Input Output system) is the program used by a personal computer microprocessor to start the computer system after turning it on. It also manages the data flow between the computer’s operating system and connected devices such as the hard drive, video adapter, keyboard, mouse and printer.

The BIOS is an integral part of your computer and is a program made accessible to the microprocessor on a Erasable programmable read only memory (EPROM) chip. When you turn on your computer, the microprocessor passes control to the BIOS program, which is always in the same place on the EPROM.

When the BIOS starts up (boots up) your computer, it first determines whether all of the attachments are in place and operational, then loads the operating system (or key parts of it) into RAM ) from your computer from your hard drive. disk or floppy drive.

Change of calendar date in BIOS is not reflected

You will experience this problem based on the following scenario:

• In the computer BIOS, you change the calendar date to a value earlier than the date displayed by Windows.
• You save the change and restart Windows.

In this scenario, the Windows date setting does not reflect the change you made to the calendar date in the BIOS.

According to Microsoft, this behavior is inherent in design. Windows considers the fact that time does not go back. In addition, the BIOS of a laptop or laptop can report a date earlier than the Windows date if the battery is faulty or dead. In such cases, the BIOS date and time are not reliable.

Also, this behavior does not affect changes to the calendar date in the BIOS if the new date is later than the date reported by Windows.

To resolve this issue, if you need to change the calendar date on your computer, use Windows settings to make the change instead of changing the date in the BIOS. This change will be reflected on multiple reboots.
