Republican Calendar

A Rust library for the French Republican Calendar.

Features

• Bi-directional conversion between Gregorian and Republican calendar dates.
• Full name and formatting support for Republican dates and months.
• No std dependency (only relies on chrono for date calculations).

Usage

use republican_calendar::date::Date;

fn main() {
    // Get today's date in Republican calendar
    let today = chrono::Local::now().date_naive();
    let rc_today = Date::from_gregorian(today);
    println!("Today is {}", rc_today);
    
    // Create a Republican calendar date
    let date = Date::try_from_ymd(1, 1, 1).unwrap(); // 1 Vendémiaire Year 1
    let gregorian = date.to_gregorian(); // Convert to Gregorian
}

About the Calendar

The French Republican Calendar uses a new era beginning on September 22, 1792. Each year consists of twelve 30-day months plus 5-6 complementary days called Sans-culottides. Each month and day has a unique name, about which you can read more here.
