Chronic is a natural language date/time parser written in pure Ruby.

A simple Ruby natural language parser for elapsed time. (For example, 4 hours and 30 minutes, 6 minutes 4 seconds, 3 days, etc.) Returns all results in seconds. Will return an integer unless you get tricky and need a float. (4 minutes and 13.47 seconds, for example.) The reverse can also be performed via the output method.

A dirt simple library for parsing and formatting human readable dates

Extracts date, time, and message information from naturally worded text.

Tickle is a date/time helper gem to help parse natural language into a recurring pattern. Tickle is designed to be a compliment of Chronic and can interpret things such as "every 2 days, every Sunday, Sundays, Weekly, etc.
