Usage

Ethiopian Calendar

Ethiopian calendar can be implemented by creating EthiopianCalendar instance.

   import 'package:ecDart/calendar/ethiopian_calendar.dart';

   // creating instance with paramters
   var ec = new EthiopianCalendar(year: 2015, month: 1, day: 1);    
   print(ec.month_name);                                               //  "መስከረም"
   print(ec.isHoliday);                                                //  true
   print(ec.holiday_name);                                             //  "አዲስ አመት"

   // creating instance that contains the current date
   var now = new EthiopianCalendar.now();                             
   print(now.year);                                                    //  2015
   print(now.month_name);                                              //  "ሰኔ"
   print(now.day);                                                     //  3
   print(now.day_name);                                                // "ቅዳሜ"

EthiopianCalendar instance contains method called toGC() which is used to convert a given Ethiopian date to Gregorian.

  import 'package:ecDart/calendar/ethiopian_calendar.dart';
  
  // creating instance that contains the current date
  var now = new EthiopianCalendar.now();         

  // converting the current date to gregorian                    
  var now_gc = now.toGC();                                          
  print(now_gc.year);                                                 //  2023
  print(now_gc.month_name);                                           //  "June"
  print(now_gc.day);                                                  //  10
  print(now_gc.day_name);                                             // "Saturday"

EthiopianCalendar instance contains methods to get the next month, previous month, next year and previous year in the form of Ethiopian date.

   import 'package:ecDart/calendar/ethiopian_calendar.dart';

   // creating instance that contains the current date
   var now = new EthiopianCalendar.now();                             
   
   // creating the next Ethiopian month  
   var next_month = now.nextMonth();
   print(next_month.year);                                            //  2015
   print(next_month.month_name);                                      //  "ኃምሌ"
   print(next_month.day);                                             //  3

   // creating the previous Ethiopian year
   var previous_year = now.previousYear();
   print(previous_year.year);                                         //  2014
   print(previous_year.month_name);                                   //  "ሰኔ"
   print(previous_year.day);                                          //  3

Gregorian Calendar

Gregorian calendar can be implemented by creating GregorianCalendar instance.

   import 'package:ecDart/calendar/gregorian_calendar.dart';

   // creating instance with paramters
   var gc = new GregorianCalendar(year: 2023, month: 6, day: 8);
   print(gc.year);                                                     // 2023
   print(gc.month_name);                                               // "June"
   print(gc.day_name);                                                 // "Thursday"

   // creating instance that contains the current date
   var now = new GregorianCalendar.now();
   print(now.year);                                                    // 2023
   print(now.month_name);                                              // "June"
   print(now.day_name);                                                // "Saturday"

GregorianCalendar instance contains method called toEC() which is used to convert a given Gregorian date to Ethiopian.

  import 'package:ecDart/calendar/gregorian_calendar.dart';
  
  // creating instance that contains the current date
  var now = new GregorianCalendar.now();

  // converting the current date to gregorian
  var ec = now.toEC();
  print(ec.year);                                                       // 2015
  print(ec.month_name);                                                 // "ሰኔ"
  print(ec.day_name);                                                   // "ቅዳሜ"

GregorianCalendar instance contains methods to get the next month, previous month, next year and previous year in the form of Gregorian date.

   import 'package:ecDart/calendar/gregorian_calendar.dart';

   // creating instance that contains the current date
   var now = new GregorianCalendar.now();                             
   
   // creating the next Gregorian month  
   var next_month = now.nextMonth();
   print(next_month.year);                                               //  2023
   print(next_month.month_name);                                         //  "July"
   print(next_month.day);                                                //  10

   // creating the previous Gregorian year
   var previous_year = now.previousYear();
   print(previous_year.year);                                            //  2022
   print(previous_year.month_name);                                      //  "June"
   print(previous_year.day);                                             //  10

Utilities

ecDart contains utility functions for calculating month and day of movable and non movabele holidays.

   import 'package:ecDart/utils/helpers/util.dart';

   // getting all holidays of a given Ethiopian year 
   var holidays = getHolidays(2015);

   // getting holiday name of specific Ethiopian date
   var holiday = getHoliday("የካቲት", 23, 2015);
   print(holiday);                                                        // "አደዋ" (non moviable holiday)

   var fasika = getHoliday("ሚያዝያ", 8, 2015);
   print(fasika);                                                        // "ትንሳኤ" (moviable holiday)

Holidays model

   [
      {
         "name": "name of the holiday",
         "month": "month name of the holiday",
         "day": "day of the holiday"
      }
   ]
