Birthday Paradox Simulation

🎂 Birthday Paradox Simulation (using Python)

📌 Introduction

The Birthday Paradox is a probability concept that shows how surprisingly likely it is for two people in a group to share the same birthday. Even in relatively small groups, the chances of a match are much higher than most people intuitively expect.

This Python project uses a Monte Carlo simulation to repeatedly generate random birthdays and estimate the probability of at least one shared birthday in a group.

🚀 Features

• Generates random birthdays for a given number of people
• Detects if any two birthdays match
• Runs 100,000 simulations to estimate real probability
• Simple command-line interaction
• Uses only built-in Python libraries (datetime, random)

💻 Example

How many birthdays shall I generate? (Max 100)
> 23

Here are 23 birthdays:
Jan 1, Mar 5, Jul 12, ...

In this simulation, multiple people have a birthday on Jul 12

Generating 23 random birthdays 100,000 times...
100,000 simulations run.

Out of 100,000 simulations of 23 people, there was a
matching birthday in that group 50789 times.
That means ~50.79% probability.
