The words Bahire Hasab originate from the ancient language of Ge'ez, ( Arabic: Abu Shakir) is a time-tracking method, devised by the 12th pope of Alexandria, Pope St. Dimitri.

What does it mean?

"Bahire Hasab /'bəhrɛ həsəb'/ " simply means "An age with a descriptive and chronological number". In some books it can also be found as "Hasabe Bahir", in a sense giving time an analogy, resembling a sea.

This package allows developers to implement Ethiopian Calendar and Datetime System in their application(s)`.

This package is implemented using the UNIX EPOCH which means it's not a conversion of any other calendar system into Ethiopian, for instance, Gregorian Calendar.

Unix Epoch is measured using milliseconds since 01 Jan, 1970 UTC. In unix epoch leap seconds are ignored.

Prerequisites

Before you begin, ensure you have met the following requirements:

  • equatable= ^1.1.0

Getting started

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  abushakir: "^0.0.1"

In your library add the following import:

import 'package:abushakir/abushakir.dart';

Example

   /**
   * Ethiopian Datetime Module [EtDatetime]
   */
  EtDatetime now = new EtDatetime.now(); // => 2012-07-28 17:18:31.466
  print(now.date); // => {year: 2012, month: 7, day: 28}
  print(now.time); // => {h: 17, m: 18, s: 31}

  EtDatetime covidFirstConfirmed = new EtDatetime(year: 2012, month: 7, day: 4);
  EtDatetime covidFirstConfirmedEpoch =
      new EtDatetime.fromMillisecondsSinceEpoch(covidFirstConfirmed.moment);

  EtDatetime covidFirstDeath = EtDatetime.parse("2012-07-26 23:00:00");

  /// Comparison of two EtDatetime Instances
  Duration daysWithOutDeath = covidFirstConfirmed.difference(covidFirstDeath);

  assert(daysWithOutDeath.inDays == -22, true); // 22 days

  assert(covidFirstDeath.isAfter(covidFirstConfirmed), true);

  assert(covidFirstDeath.isBefore(now), true);

  assert(covidFirstConfirmed.isAtSameMomentAs(covidFirstConfirmedEpoch), true);

  /**
   * Ethiopian Calendar Module [ETC]
   */
  ETC ethiopianCalendar = new ETC(year: 2012, month: 7, day: 4);

  ///
  print(ethiopianCalendar.monthDays(geezDay: true, weekDayName:true)); // Iterable Object of the given month
  print(ethiopianCalendar.monthDays().toList()[0]); // => [2012, 7, ፩, አርብ]
  // [year, month, dateNumber, dateNameIndex], Monday as First weekday

  print(ethiopianCalendar.nextMonth); // => ETC instance of nextMonth, same year
  print(ethiopianCalendar.prevYear); // => ETC instance of prevYear, same month

  /**
   * Bahire Hasab Module [BahireHasab]
   */
  BahireHasab bh = BahireHasab(year: 2011);
//  BahireHasab bh = BahireHasab(); // Get's the current year

  print(bh.getEvangelist(returnName: true)); // => ሉቃስ

  print(bh.getSingleBealOrTsom("ትንሳኤ")); // {month: ሚያዝያ, date: 20}

  bh.allAtswamat; // => List of All fasting and Movable holidays

  /**
   * Arabic or English number (1,2,3...) to Ethiopic or GE'EZ (፩, ፪, ፫...) number Converter
   */

  var input= [1, 10, 15, 20, 25, 78, 105, 333, 450, 600, 1000, 1001, 1010, 1056, 1200, 2013, 9999, 10000];

  for (var arabic in input) {
     print(ConvertToEthiopic(arabic)); // [፩, ፲, ፲፭, ፳, ፳፭, ፸፰, ፻፭, ፫፻፴፫, ፬፻፶, ፮፻, ፲፻, ፲፻፩, ፲፻፲, ፲፻፶፮, ፲፪፻, ፳፻፲፫, ፺፱፻፺፱, ፻፻]
  }
