You need another dragon for Excel and its two date systems.
I thought about that, but decided to leave it as an exercise for the reader.
Don’t forget that Integer8 (the middle dragon) counts increments of 100 nanoseconds, because… reasons.
And don’t forget that 1900 still is a leap year in Excel.
I don’t know what you’re trying to do with Excel, but based on your posts, I can only wish you good luck. I’m happy to say that I have been able to outsource low level parsing to third party libraries for my needs so far. Well, except the interpreting semantic formatting part. That was on me.

Thank you! Saying this finally made me realize why I always need to add/subtract one day when I’m trying to convert dates to and from the Excel representation. 🤦

Hahaha!!!
Today I watched a Java server crash because a library decided it needed more than 3GB of heap space to read a 10MB file. That was after manually removed background colors from around 100,000 cells, which apparently caused the parser to create even more objects in its internal representation of the sheet.
Yeah, I get it. I’ve had many libraries fail me in as many ways, which is why I consider it lucky to not have to implement my own. I work in .net these days, but there have been times where I had to just dig into the xml inside the xlsx and use xml tools. Those were mostly one-offs, thankfully.
Back when I did Java I had a frustrating experience with IBM’s libxml causing our app to crash after several days due to a memory leak. I didn’t have access to the production environment so it took me probably 3 weeks to find the cause and only after digging through a crash dump provided by the sysadmin. Not related, but you triggered my traumatic memory :)
FYI the aliens who built the pyramids actually had that tech stack.
