fuzzy timestamp parsing with Python

Check out this open source module: parsedatetime

dateparser

Usage:

>>> import dateparser
>>> dateparser.parse('2 minutes ago')
datetime.datetime(2018, 11, 27, 13, 44, 54, 993170)
>>> dateparser.parse('yesterday at 15:12')
datetime.datetime(2018, 11, 26, 15, 12)

I have been dabbling with this using pyparsing - you can find my latest attempt here. It works for these test cases:

today
tomorrow
yesterday
in a couple of days
a couple of days from now
a couple of days from today
in a day
3 days ago
3 days from now
a day ago
now
10 minutes ago
10 minutes from now
in 10 minutes
in a minute
in a couple of minutes
20 seconds ago
in 30 seconds
20 seconds before noon
20 seconds before noon tomorrow
noon
midnight
noon tomorrow
