It is way too early

They currently go on sale one month in advance

The previous comments are correct. If you only have one day consider buying the Super Pass. I found a blog that really explains how they work. https://www.thegeographicalcure.com/post/decoding-rome-s-super-pass. Decoding Rome’s S.U.P.E.R. Pass for Restricted Archaeological Sites from Nov 10, 2021.
Hope this helps.

Are tickets to see the Domus Aurea – Nero’s Golden Palace separate from the Forum?

The Domus Aurea tickets are a separate ticket. For sale directly from the Coop
Culture site here: https://www.coopculture.it/en/products/domus-aurea-experience/

They go on sale 30 days out. I’ve been watching for our October date forever and we’re finally getting close. They do sell out though. And they’re only open Fri, Sat and Sun. And then some Fridays are blocked out in red and so I’m thinking they’re not open those Fridays. For example - September tickets are now on sale and two Fridays in September are blocked out in red.

...."The Forum Pass Super Ticket is valid for 30 days from the booking day". Crystal

Thanks for all the responses with some good info. I just booked our 2 pm +/- Colosseum / Forum/ Palantine entry for Wednesday at the end of October. There were plenty of time spots available. 2 people €36. Done.
We will have an opportunity 8Oct to scope out what else we would like to do in Rome at the end of our Northen Italy trip. We will also have half a day 7 & 9 Oct before heading north.
