Birth Yama invalid

[sengiv]

🤔 having trouble coding "Birth Yama" number
below is the code....anybody got a clue, please chime in 🙏
(AI has obvious failed me here 🤣)

/// <summary>
/// yama works out to 2 hrs. 24 mts. of our modern time.
/// It is to be noted that the beginning of the day is
/// reckoned from Sun rise to Sun set in Hindu system. Similarly
/// night is reckoned from Sun set to Sun rise on the following
/// day, thus consisting of 24 hours for one day.
/// The timings of the five Yamas are the same during day
/// and night
/// for Pancha Pakshi
/// </summary>
public static BirthYama BirthYama(Time birthTime)
        {
      
            // Extract the time component from the DateTimeOffset
            DateTimeOffset dto = birthTime.GetLmtDateTimeOffset();
            TimeSpan inputTime = dto.TimeOfDay;

            // Parse the start and end times
            var sunriseStd = SunriseTime(birthTime).GetLmtDateTimeOffset();
            TimeSpan start = sunriseStd.TimeOfDay;
            var sunsetStd = SunsetTime(birthTime).GetLmtDateTimeOffset();
            TimeSpan end = sunsetStd.TimeOfDay;

            // Calculate the length of each piece
            //TimeSpan pieceLength = (end - start) / 5;
            TimeSpan pieceLength = TimeSpan.FromHours(2.4);

            // Find out which piece the input time falls under
            for (int i = 0; i < 5; i++)
            {
                TimeSpan yamaStartTime = start + pieceLength * i;
                TimeSpan yamaEndTime = start + pieceLength * (i + 1);

                if (inputTime >= yamaStartTime && inputTime <= yamaEndTime)
                {
                    return new BirthYama(i + 1, yamaStartTime, yamaEndTime);
                }

                Console.WriteLine($"{i + 1} -- {yamaStartTime} -- {yamaEndTime}");
                if (i == 4)
                {
                    Console.WriteLine("last");
                }
            }

            //if reach here than fail!
            //return new BirthYama(1, new TimeSpan(), new TimeSpan());

        }
