When: A Natural Language Date/time Parser with Pluggable Rules
when
whenis a natural language date/time parser with pluggable rules and merge strategies
Examples
- tonight at 11:10 pm
- at Friday afternoon
- the deadline is next tuesday 14:00
- drop me a line next wednesday at 2:25 p.m
- it could be done at 11 am past tuesday
Check EN, RU and BR rules and tests for them, for more examples.
Needed rule not found? Open an issue with the case and it will be added asap.
How it works
Usually, there are several rules added to the parser's instance for checking. Each rule has its own borders - length and offset in provided string. Meanwhile, each rule yields only the first match over the string. So, the library checks all the rules and extracts a cluster of matched rules which have distance between each other less or equal to options.Distance, which is 5 by default. For example:
on next wednesday at 2:25 p.m.
└──────┬─────┘ └───┬───┘
weekday hour + minute
So, we have a cluster of matched rules - "next wednesday at 2:25 p.m." in the string representation.
After that, each rule is applied to the context. In order of definition or in match order, if options.MatchByOrder is set to true(which it is by default). Each rule could be applied with given merge strategy. By default, it's an Override strategy. The other strategies are not implemented yet in the rules. Pull requests are welcome.
Usage
w := when.New(nil)
w.Add(en.All...)
w.Add(common.All...)
text := "drop me a line in next wednesday at 2:25 p.m"
r, err := w.Parse(text, time.Now())
if err != nil {
// an error has occurred
}
if r == nil {
// no matches found
}
fmt.Println(
"the time",
r.Time.String(),
"mentioned in",
text[r.Index:r.Index+len(r.Text)],
)
Distance Option
w := when.New(nil)
w.Add(en.All...)
w.Add(common.All...)
text := "February 23, 2019 | 1:46pm"
// With default distance (5):
// February 23, 2019 | 1:46pm
// └───┬───┘
// distance: 9 (1:46pm will be ignored)
r, _ := w.Parse(text, time.Now())
fmt.Printf(r.Time.String())
// "2019-02-23 09:21:21.835182427 -0300 -03"
// 2019-02-23 (correct)
// 09:21:21 ("wrong")
// With custom distance (10):
w.SetOptions(&rules.Options{
Distance: 10,
MatchByOrder: true})
r, _ = w.Parse(text, time.Now())
fmt.Printf(r.Time.String())
// "2019-02-23 13:46:21.559521554 -0300 -03"
// 2019-02-23 (correct)
// 13:46:21 (correct)
State of the project
The project is in a more-or-less complete state. It's used for one project already. Bugs will be fixed as soon as they will be found.
TODO
- readme: describe all the existing rules
- implement missed rules for these examples
- add cli and simple rest api server(#2)

Python Datetime Tutorial: Manipulate Times, Dates, and Time Spans
Dealing with dates and times in Python can be a hassle. Thankfully, there’s a built-in way of making it easier: the Python datetime module.
datetime helps us identify and process time-related elements like dates, hours, minutes, seconds, days of the week, months, years, etc. It offers various services like managing time zones and daylight savings time. It can work with timestamp data. It can extract the day of the week, day of the month, and other date and time formats from strings.

A Simple Ruby Natural Language Parser for Elapsed Time
Chronic Duration
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 accomplished with the output method. So pass in seconds and you can get strings like 4 mins 31.51 secs (default format), 4h 3m 30s, or 4:01:29.
Usage
>> require 'chronic_duration'
=> true
>> ChronicDuration.parse('4 minutes and 30 seconds')
=> 270
>> ChronicDuration.parse('0 seconds')
=> nil
>> ChronicDuration.parse('0 seconds', :keep_zero => true)
=> 0
>> ChronicDuration.output(270)
=> 4 mins 30 secs
>> ChronicDuration.output(0)
=> nil
>> ChronicDuration.output(0, :keep_zero => true)
=> 0 secs
>> ChronicDuration.output(270, :format => :short)
=> 4m 30s
>> ChronicDuration.output(270, :format => :long)
=> 4 minutes 30 seconds
>> ChronicDuration.output(270, :format => :chrono)
=> 4:30
>> ChronicDuration.output(1299600, :weeks => true)
=> 2 wks 1 day 1 hr
>> ChronicDuration.output(1299600, :weeks => true, :units => 2)
=> 2 wks 1 day
>> ChronicDuration.output(45*24*60*60 + 15*60, :limit_to_hours => true)
=> 1080 hrs 15 mins
>> ChronicDuration.output(1299600, :weeks => true, :units => 2, :joiner => ', ')
=> 2 wks, 1 day
>> ChronicDuration.output(1296000)
=> 15 days
Nil is returned if the string can't be parsed
Examples of parse-able strings:
- '12.4 secs'
- '1:20'
- '1:20.51'
- '4:01:01'
- '3 mins 4 sec'
- '2 hrs 20 min'
- '2h20min'
- '6 mos 1 day'
- '47 yrs 6 mos and 4d'
- 'two hours and twenty minutes'
- '3 weeks and 2 days'
ChronicDuration.raise_exceptions can be set to true to raise exceptions when the string can't be parsed.
>> ChronicDuration.raise_exceptions = true
=> true
>> ChronicDuration.parse('4 elephants and 3 Astroids')
ChronicDuration::DurationParseError: An invalid word "elephants" was used in the string to be parsed.

TODO
- Benchmark, optimize
- Context specific matching (E.g., for '4m30s', assume 'm' is minutes not months)
- Smartly parse vacation-like durations (E.g., '4 days and 3 nights')
- :chrono output option should probably change to something like 4 days 4:00:12 instead of 4:04:00:12
- Other locale support
