Plan around the calendar
Collect materials while they are available: ordinary blocks gradually give way to rarer and end-game resources. Day 101 starts the sequence again. Construction outside the designated changing layers is excluded from the conversion.
Version 3
The supplied world adds a village with two blacksmiths and an End portal at X=1500, Z=1500. You can attempt the challenge alone or with friends. Retain the included behavior pack so the daily changes continue to work.
