Parsing fails for dddd HH:mm for hours 00 to 06.

[ZachGawlik]

EDIT:

After briefly looking into the code, the invalid date is coming from moment.utc.apply(null, ['Tuesday 01:03', 'dddd HH:mm']);. I closed this ticket in favor of moment/moment#4227

Example statements

Either read below or see them in action on my JSFiddle. Note: the invalid date edge case seems to depend on your current system time, so they might not display as Invalid at all times.

Edge case errors. All statements below return invalid date.

moment.tz('Saturday 06:59', 'dddd HH:mm', 'America/New_York'); 
moment.tz('Tuesday 01:03', 'dddd HH:mm', 'America/New_York');
moment.tz('Tuesday 01:03', 'dddd HH:mm', 'America/Los_Angeles');

Times 07:00 and later as well as date strings without the day of week are parsed correctly. All statements below return valid dates.

moment.tz('Saturday 07:00', 'dddd HH:mm', 'America/New_York'); 
moment.tz('06:59', 'HH:mm', 'America/New_York');
moment.tz('December 01:03', 'MMMM HH:mm', 'America/New_York');

Moment without timezone returns a valid date.

moment('Saturday 06:59', 'dddd HH:mm')
