ArgumentOutOfRangeException for Aggregation with PeriodSize.Month

the problem

Calling public static IEnumerable<Quote> Aggregate<TQuote>(this IEnumerable<TQuote> quotes, PeriodSize newSize) with PeriodSize.Month returns a ArgumentOutOfRangeException. Aggregation by other periods in lower time frame (Daily, Weekly) works as expected.

to reproduce

1. Create a IEnumerable<Quote> quotes collection with hourly or daily data
2. Call quotes.Aggregate(PeriodSize.Month)

Error message(s):

System.ArgumentOutOfRangeException
  HResult=0x80131502
  Message=Historical quotes Aggregation must use a new size value that is greater than zero (0). Arg_ParamName_Name
ArgumentOutOfRange_ActualValue

[SvenSkrabal]

The PeriodSize enum value is converted to a TimeSpan object with an extension method:

public static IEnumerable<Quote> Aggregate<TQuote>(
        this IEnumerable<TQuote> quotes,
        PeriodSize newSize)
        where TQuote : IQuote
    {
        // parameter conversion
        TimeSpan newTimeSpan = newSize.ToTimeSpan();

        // convert
        return quotes.Aggregate(newTimeSpan);
    }

This extension method is lacking a case for PeriodSize.Month:

// PERIOD-SIZE to TIMESPAN CONVERSION
    internal static TimeSpan ToTimeSpan(this PeriodSize periodSize)
    {
        return periodSize switch
        {
            PeriodSize.OneMinute => TimeSpan.FromMinutes(1),
            PeriodSize.TwoMinutes => TimeSpan.FromMinutes(2),
            PeriodSize.ThreeMinutes => TimeSpan.FromMinutes(3),
            PeriodSize.FiveMinutes => TimeSpan.FromMinutes(5),
            PeriodSize.FifteenMinutes => TimeSpan.FromMinutes(15),
            PeriodSize.ThirtyMinutes => TimeSpan.FromMinutes(30),
            PeriodSize.OneHour => TimeSpan.FromHours(1),
            PeriodSize.TwoHours => TimeSpan.FromHours(2),
            PeriodSize.FourHours => TimeSpan.FromHours(4),
            PeriodSize.Day => TimeSpan.FromDays(1),
            PeriodSize.Week => TimeSpan.FromDays(7),
            _ => TimeSpan.Zero
        };
    }
