This was my tenth(!) year building 25 days of puzzles for #AdventOfCode. You can solve them all for free! Most people write code to solve them, but you can solve them however you like. I hope they help people become better programmers. 🌟

The first puzzle comes out in two hours: https://adventofcode.com/

Advent of Code 2025

@ericwastl The first problem can be solved with a spreadsheet program of your choice 🙂

Part 2 needs a more powerful language.

@gunchleoc
Day 1 part 2 can also be solved with just a spreadsheet 😉
@ericwastl
@incredobler @ericwastl Probably. I just didn't feel like learning a new programming language or inserting tons of blank cells for aligning stuff
