Configuring the default hemisphere should be possible in the future. -### Day times +#### *Day times* There are some hardcoded times for *'lunch time'* and others, but mainly, a day begins at `12:00am` and ends at `11:59pm` - the last millisecond of the day. -### Invalid dates +#### *Invalid dates* compromise will tag anything that looks like a date, but not validate the dates until they are parsed. * *'january 34th 2020'* will return **Jan 31 2020**. * *'tomorrow at 2:62pm'* will return just return 'tomorrow'. * *'6th week of february* will return the 2nd week of march. * Setting an hour that's skipped, or repeated by a DST change will return the closest valid time to the DST change. -### Inclusive/exclusive ranges +#### *Inclusive/exclusive ranges* *'between january and march'* will include all of march. This is usually pretty-ambiguous normally. -### Misc +#### *Misc* * *'thursday the 16th'* - will set to the 16th, even if it's not thursday * *'in a few hours/years'* - in 2 hours/years * *'jan 5th 2008 to Jan 6th the following year'* - date-range explicit references * assume *'half past 5'* is 5pm + +
