javascript - 获取波斯月的最后一天 + 解决方案

Question

在浏览网页后，我找不到任何功能来执行此操作，我有可行的个人解决方案。也许它对某人有用。

**使用 Moment 插件转换日期。***moment(currentPersianDate).clone().endof('month').format('YYYY/MM/DD') => 不适用于波斯语日期

  function GetLastDayOfPersianMonth(calendar) {
            const currentDate = new Date();
            const currentPersianDate = moment(currentDate).locale('fa').format('YYYY/M/D');
            const splitDate = currentPersianDate.split("/");
            const year = splitDate[0];
            const month = splitDate[1];
            const lastDayOfPersianMonth = CalculateLeapYear(month, year);
    
            const endPersianMonth = year + "/" + month + "/" + lastDayOfPersianMonth;
        };

    function CalculateLeapYear(month, year) {
            if (month <= 6) {
                return 31;
            }
            if (month > 6 && month < 12) {
                return 30;
            }

            const leapMatch = [1, 5, 9, 13, 17, 22, 26, 30];
            const number = year % 33;
            const isLeap = leapMatch.includes(number);
           
            if (month == 12 && !isLeap) {
                return 29;
            }
            if (month == 12 && isLeap) {
                return 30;
            }
        }

您可以在 C# 中使用此代码我的网站 https://mohammadhosseinaref.ir

        public static string PersianDayOfWeek(DayOfWeek dayOfWeek)
    {
        switch (dayOfWeek)
        {
            case DayOfWeek.Sunday:
                return "یکشنبه";
            case DayOfWeek.Monday:
                return "دوشنبه";
            case DayOfWeek.Tuesday:
                return "سه شنبه";
            case DayOfWeek.Wednesday:
                return "چهار شنبه";
            case DayOfWeek.Thursday:
                return "پنج شنبه";
            case DayOfWeek.Friday:
                return "جمعه";
            case DayOfWeek.Saturday:
                return "شنبه";
            default:
                return null;
        }
    }

      public static Dictionary<int, string> ListOfPersianDayOfMonth(int month, int years)
    {
        Dictionary<int, string> dicDays = new Dictionary<int, string>();

        PersianCalendar p = new PersianCalendar();

        var dates = Enumerable.Range(1, p.GetDaysInMonth(years, month))
               .Select(day => ParsePersianToGorgian(years + "/" + month + "/" + day))
               .ToList();

        foreach (var item in dates)
        {
            var day = GeorgianToPersian(item.Value, ShowMode.OnlyDate);
            dicDays.Add(int.Parse(day.Split('/')[2]), DayPersian(item.Value.DayOfWeek) + " " + day);
        }
        return dicDays;
    }
