Split date range into date range chunks

Question

I am looking for a method of splitting a date range into a series of date ranges by chunk size of days. I am planning on using this to buffer calls to a service which if th

Your code looks fine for me. I don't really like the idea of while(true)
But other solution would be to use enumerable.Range:

public static IEnumerable> SplitDateRange(DateTime start, DateTime end, int dayChunkSize)
{
    return Enumerable
          .Range(0, (Convert.ToInt32((end - start).TotalDays) / dayChunkSize +1))
          .Select(x => Tuple.Create(start.AddDays(dayChunkSize * (x)), start.AddDays(dayChunkSize * (x + 1)) > end
                                                                       ? end : start.AddDays(dayChunkSize * (x + 1))));
}  

or also, this will also work:

public static IEnumerable> SplitDateRange(DateTime start, DateTime end, int dayChunkSize)
{
    var dateCount = (end - start).TotalDays / 5;
    for (int i = 0; i < dateCount; i++)
    {
        yield return Tuple.Create(start.AddDays(dayChunkSize * i)
                                , start.AddDays(dayChunkSize * (i + 1)) > end 
                                 ? end : start.AddDays(dayChunkSize * (i + 1)));
    }
}

I do not have any objects for any of the implementations. They are practically identical.
