You need that in the The Rotary Calendar Puzzle. But first make sure you have the day and month. Make your way to Reception to get to it. Don't worry I will help you in the Rotary Calendar Puzzle. The Rotary Calendar Puzzle:
This puzzle is already two-thirds solved. We have the day, the 12th, and
The month, June, but we don't have the year. The Grady family fell on
Hard times after Helen was committed for attacking Travis. All Richard's
Lamentations spring from that event. If you remember the patient memos
From the sanitarium, they're dated 1960 and 1961.

Trying both years and figuring out which one is right is easy. However,
If you want definite proof that the answer is 1961, check Travis' lucky
Quarter. It has the number 61 etched into it and is a keepsake he's had
From when his parents died. It's not clear when Helen died, and we don't
Know what Richard did to himself (yet), but it's clear that both his
Parents "died" in some form or another in the year 1961.

The full date on the rotary calendar is 06/12/1961. A small depression
Opens. The wedding ring fits there nicely. This reveals the ROOM 500
KEY behind you.

Make your way back to the mirror in Room 503, watching out for the second
Caliban now roaming about. You can only enter Room 500 from the Otherworld. A
Cutscene will take you to the door, which leads to a long staircase. Equip a
Firearm before entering the door below.

That's it is your way through there.. Good luck! Hope this helps! Free to ask me anytime...
