Expand description

Dates for the Badí’ (Bahá’í) calendar and conversions between Badí’ and Gregorian dates.

See The Bahá’í Calendar at bahai.org.

§Example: create BadiDate

use badi_date::{BadiDate, BadiMonth, BadiDateOps};
let badi_date = BadiDate::new(181, BadiMonth::Month(19), 19).unwrap();
assert_eq!(
    BadiDate::new(182, BadiMonth::Month(1), 1).unwrap(),
    badi_date.add_days(1),
);

§Example: create LocalBadiDate from local chrono::DateTime<Tz> and geo Coordinates

use badi_date::{LocalBadiDate, BadiMonth, Coordinates, FromDateTime};
use chrono::TimeZone;
let denver: chrono_tz::Tz = "America/Denver".parse().unwrap();
let coords = Some(Coordinates::new(39.613319, -105.016647).unwrap());
let date = denver.with_ymd_and_hms(2024, 3, 19, 18, 0, 0).unwrap();
let badi_date = LocalBadiDate::from_datetime(date, coords).unwrap();
assert_eq!(
    LocalBadiDate::new(180, BadiMonth::Month(19), 19, denver, coords).unwrap(),
    badi_date,
);

§Example: create LocalBadiDate from local chrono::DateTime<Tz> without Coordinates

use badi_date::{LocalBadiDate, BadiMonth, Coordinates, FromDateTime};
use chrono::TimeZone;
let denver: chrono_tz::Tz = "America/Denver".parse().unwrap();
let date = denver.with_ymd_and_hms(2024, 3, 19, 18, 0, 0).unwrap();
let badi_date = LocalBadiDate::from_datetime(date, None).unwrap();
assert_eq!(
    LocalBadiDate::new(181, BadiMonth::Month(1), 1, denver, None).unwrap(),
    badi_date,
);

Structs§

  • LocalBadiDate
    A structure that holds a date in the Badí‘ (Bahá’í) calendar with associated time zone and optional coordinates
