Hi Gloria, welcome to TSG.
It sounds as if your BIOS settings are wrong in the CMOS area.
This is straightforward to correct.
If you say you are adjusting it each day I assume you mean via the Adjust/Date time menu on bottom right within the time display.
If so it is not modifying the CMOS.
You will have to get to that directly by shutting down your PC then restarting, pressing the Delete key (this is the usual one but check your PC manual to see if its any other, like Esc, F2, etc) during the boot process. (Tap it repeatedly once things are getting started but before the Windows screen appears)
This will take you to the BIOS menu(or directly to CMOS)
Choose the CMOS setup option.
In there you will find a field where you can type in the correct current time and date, usually based on the 24 hour clock, or with an am/pm indicator.
Follow the menus, saving changes, to Exit.
Next time you start up you should be okay.
