About Gree.do

Understanding Star Wars Epoch Time and Galactic Time Systems

What is Gree.do?

Gree.do is a dynamic web service that provides both real-world and Star Wars-themed timestamps through a beautiful animated interface and REST API endpoints. It combines practical time-keeping with the rich lore of the Star Wars universe, offering multiple galactic time systems for developers, fans, and anyone who wants to add a touch of galactic magic to their projects.

Essential Truth

Han shot first.

This fundamental fact anchors our understanding of the galaxy and serves as the cornerstone of all temporal calculations within the Gree.do system.

SWET (Star Wars Epoch Time)

The Foundation of Galactic Time

SWET (Star Wars Epoch Time) is a custom time system designed specifically for this project, similar to Unix time but with a galactic twist. SWET counts seconds since the theatrical release of Star Wars: A New Hope.

SWET Specifications:

Epoch Start: 1977-05-25 00:00:00 UTC
Unit: Seconds
Current SWET: Loading...
Years Since Release: Loading...

Why May 25, 1977?

This date marks the theatrical release of Star Wars in the United States, making it the perfect anchor point for galactic time. Just as Unix time starts from January 1, 1970 (the "Unix Epoch"), SWET starts from the moment that changed science fiction forever.

CGT (Combine Galactic Time)

Combine Galactic Time is an established time system used by the Star Wars Combine community. It provides a standardized way to represent time across the galaxy.

CGT Specifications:

Year Length: 365 days
Day Length: 24 hours
Day Range: 1-365
Current CGT: Loading...

CGT Epoch Modes:

  • Current Mode: CGT(0,1,0,0,0) = 1998-12-03 07:00:00 UTC
  • Legacy Mode: CGT(0,1,0,0,0) = 1998-12-03 00:00:00 UTC

Other Star Wars Time Systems

GSC

BBY/ABY

Before/After Battle of Yavin

Timeline system centered around the pivotal Battle of Yavin, where Luke Skywalker destroyed the first Death Star.

"The ability to destroy a planet is insignificant next to the power of the Force."

BTC/ATC

Before/After Treaty of Coruscant

Historical dating system based on the Treaty of Coruscant, marking significant political changes in the galaxy.

GrS

TYA

Tho Yor Arrival

Ancient dating system marking the arrival of the mysterious Tho Yor ships and the founding of the Je'daii Order.

Ruusan

Ruusan Reformation

Calendar system based on the Ruusan Reformation, which reorganized the Galactic Republic after the New Sith Wars.

Technical Implementation

The Gree.do system is built using modern web technologies and follows established astronomical and time-keeping principles adapted for the Star Wars universe.

Key Features:

Deterministic: Same input = Same output
Testable: Comprehensive unit tests
Log-friendly: Multiple output formats
Human-readable: Clear, intuitive displays

Conversion Accuracy:

All time conversions are mathematically precise and follow established Star Wars lore where possible. The system handles timezone conversions automatically and supports both naive and timezone-aware datetime objects.

Using the Gree.do API

Gree.do provides two primary API endpoints for integration into your projects:

JSON API Endpoint

GET /api/v1/greedo

Returns structured JSON data perfect for web applications and API integrations.

Text/cURL Endpoint

curl http://gree.do/curl/v1/greedo

Returns human-readable plain text format ideal for command-line usage and scripts.
