Senarium
by Makushimu
Senarium changes how numbers appear in Minecraft by replacing the usual decimal digits with a base-6 sezimal system that uses only the digits 0 to 5.
What it does
Numbers across the game are rewritten in sezimal, so item counts, potion effect levels, book page numbers and F3 debug values all display in base 6. Under this system 10 in base 6 equals 6 in decimal, 11 equals 7 and 12 equals 8, which changes how every count reads on screen.
The mod covers many other numeric displays as well, including values in the Sodium options and Mod Menu screens and Minecraft version strings. Its stated goal is to keep the change simple while letting players experience the game through a different way of counting. Installation needs only Fabric, and the mod runs on the client side alone, so servers and other players do not need it. Mod Menu is an optional dependency that adds its own screens to the list.
Senarium is published for Fabric only, with one release, 1.0.1+26.1.x-beta, built for 26.1.2 on the beta channel. Files cover 26.1, 26.1.1 and 26.1.2. The code is available as public source, but the mod is licensed under All rights reserved and is not open source.
Key features
Sezimal item counts
Stack sizes and item quantities appear in base 6 wherever the game shows them, so counts read in the sezimal system instead of decimal.
Base-6 potion effects
Potion effect levels and durations are displayed in the sezimal system alongside the rest of the interface.
Book page numbers
Page numbers in written books are shown in base 6 instead of decimal.
Debug and version numbers
F3 debug values and Minecraft version strings are rewritten in sezimal, and Sodium and Mod Menu numeric fields follow the same rule.

What the author says
Minecraft normally uses the familiar decimal system with 10 digits (0-9). Senarium replaces those numbers with sezimal (base-6), which uses only the digits 0-5. That means 10 in sezimal is equal to 6 in decimal, 11 is 7, 12 is 8, and so on.
