+# The Ghost of Christmas Past 🎅🎄👻
+
+Christmas, this year, falls on a Wednesday! 
+
+But on which day did Christmas fall in years past?
+
+## Problem Description
+
+Write a Ruby class that returns the correct weekday of Christmas Day for previous years.  
+
+## Requirements and Constraints
+
+### Requirements 
+
+Your code should return the name of the day of the week that Christmas Day was:
+- Officially celebrated
+- In England
+- Using the relative local date and time
+
+### Constraints 
+
+**You may not use Ruby's `Date` or `Time` classes, nor any other third party library to perform date computations for you**. Your solution should be derived from first-principles, implementing the logic yourself.
+
+### Input Specifications
+
+See the attached tests.
+
+### Output Specifications
+
+See the attached tests. All tests must pass!
+
+## Examples and Test Cases
+
+See the attached tests.
+
+## Getting started 
+
+1. Make sure your local repository is up to date with origin and you are on the `main` branch.
+2. `bin/cleo_katas attempt christmas_day`
+3. `ruby katas/3-christmas_day/[yourname]/test.rb`
+
+
+--- 
+
+## How to run your main file 
+
+```
+bundle exec ruby katas/3-christmas_day/edward.s/main.rb
+```
+
