# HumanTime
`HumanTime` is time for humans in Python.
Sidestep tedious and error-prone code in favor of a simple, English-based DSL for specifying absolute and relative times:
HumanTime.parseTime(Input) | Input

## Installation
To install, simply use `pip`:
> python3 -m pip install HumanTime
## Usage
Behold the simplicity and elegance of `HumanTime` --
### Times
>>> import HumanTime
>>> HumanTime.parseTime('now')
datetime.datetime(2019, 5, 5, 20, 38, 10, 119936)
>>> HumanTime.parseTime('3 hours from now')
datetime.datetime(2019, 5, 5, 23, 38, 13, 120777)
>>> HumanTime.parseTime('2019-1-3')
datetime.datetime(2019, 1, 3, 0, 0)
>>> HumanTime.parseTime('three days before 2019-1-3')
datetime.datetime(2018, 12, 31, 0, 0)
>>> HumanTime.parseTime('a month after 20200131')
datetime.datetime(2020, 2, 29, 0, 0)
>>> HumanTime.parseTime('Tuesday')
datetime.datetime(2019, 5, 7, 0, 0)
>>> HumanTime.parseTime('wed')
datetime.datetime(2019, 5, 8, 0, 0)
>>> HumanTime.parseTime('Thurs after 2019-5-9')
datetime.datetime(2019, 5, 16, 0, 0)
>>> HumanTime.parseTime('2 business days before 2019-7-8')
datetime.datetime(2019, 7, 3, 0, 0)
### Durations
Fixed-length durations, representable by a `datetime.timedelta`, may also be parsed:
>>> HumanTime.parseDuration('3 seconds')
datetime.timedelta(seconds=3)
>>> HumanTime.parseDuration('3 minutes')
datetime.timedelta(seconds=180)
>>> HumanTime.parseDuration('3 days')
datetime.timedelta(days=3)
>>> HumanTime.parseDuration('three weeks')
datetime.timedelta(days=21)
### Numbers
Simple numbers (those necessary for parsing times) can also be parsed separately:
>>> HumanTime.parseCardinal('four')
4
>>> HumanTime.parseOrdinal('fourth')
4
>>> HumanTime.parseNumber('20th')
20
>>> HumanTime.parseNumber('45')
45
### Tools
Common actions are packaged as CLI tools and can be found in the `HumanTime.Tools` module.
#### `GenerateHolidayCalendar`
Generates a holiday calendar CSV with optional from and to years, headers, and observance rules.
> python3 -m HumanTime.Tools.GenerateHolidayCalendar -f 2020 -t 2021 -o
