maya 0.4.2

☤ Basic Usage of Maya

Behold, datetimes for humans!

>>> now = maya.now()
<MayaDT epoch=1481850660.9>

>>> tomorrow = maya.when('tomorrow')
<MayaDT epoch=1481919067.23>

>>> tomorrow.slang_date()
'tomorrow'

>>> tomorrow.slang_time()
'23 hours from now'

# Also: MayaDT.from_iso8601(...)
>>> tomorrow.iso8601()
'2017-02-10T22:17:01.445418Z'

# Also: MayaDT.from_rfc2822(...)
>>> tomorrow.rfc2822()
'Fri, 10 Feb 2017 22:17:01 GMT'

# Also: MayaDT.from_rfc3339(...)
>>> tomorrow.rfc3339()
'2017-02-10T22:17:01.44Z'

>>> tomorrow.datetime()
datetime.datetime(2016, 12, 16, 15, 11, 30, 263350, tzinfo=<UTC>)

# Automatically parse datetime strings and generate naive datetimes.
>>> scraped = '2016-12-16 18:23:45.423992+00:00'
>>> maya.parse(scraped).datetime(to_timezone='US/Eastern', naive=True)
datetime.datetime(2016, 12, 16, 13, 23, 45, 423992)

>>> rand_day = maya.when('2011-02-07', timezone='US/Eastern')
<MayaDT epoch=1297036800.0>

# Maya speaks Python.
>>> m = maya.MayaDT.from_datetime(datetime.utcnow())
>>> print(m)
Wed, 20 Sep 2017 17:24:32 GMT

>>> m = maya.MayaDT.from_struct(time.gmtime())
>>> print(m)
Wed, 20 Sep 2017 17:24:32 GMT

>>> rand_day.day
7

>>> rand_day.add(days=10).day
17

# Always.
>>> rand_day.timezone
UTC

# Range of hours in a day:
>>> maya.intervals(start=maya.now(), end=maya.now().add(days=1), interval=60*60)
<generator object intervals at 0x105ba5820>

# snap modifiers
>>> dt = maya.when('Mon, 21 Feb 1994 21:21:42 GMT')
>>> dt.snap('@d+3h').rfc2822()
'Mon, 21 Feb 1994 03:00:00 GMT'

☤ Advanced Usage of Maya

In addition to timestamps, Maya also includes a wonderfully powerful MayaInterval class, which represents a range of time (e.g. an event). With this class, you can perform a multitude of advanced calendar calculations with finesse and ease.

For example:

>>> from maya import MayaInterval

# Create an event that is one hour long, starting now.
>>> event_start = maya.now()
>>> event_end = event_start.add(hours=1)

>>> event = MayaInterval(start=event_start, end=event_end)

From here, there are a number of methods available to you, which you can use to compare this event to another event.

☤ Why is this useful?

• All timezone algebra will behave identically on all machines, regardless of system locale.

• Complete symmetric import and export of both ISO 8601 and RFC 2822 datetime stamps.

• Fantastic parsing of both dates written for/by humans and machines (maya.when() vs maya.parse()).

• Support for human slang, both import and export (e.g. an hour ago).

• Datetimes can very easily be generated, with or without tzinfo attached.

• This library is based around epoch time, but dates before Jan 1 1970 are indeed supported, via negative integers.

• Maya never panics, and always carries a towel.

☤ What about Delorean, Arrow, & Pendulum?

All these project complement each other, and are friends. Pendulum, for example, helps power Maya’s parsing.

Arrow, for example, is a fantastic library, but isn’t what I wanted in a datetime library. In many ways, it’s better than Maya for certain things. In some ways, in my opinion, it’s not.

I simply desire a sane API for datetimes that made sense to me for all the things I’d ever want to do—especially when dealing with timezone algebra. Arrow doesn’t do all of the things I need (but it does a lot more!). Maya does do exactly what I need.

I think these projects complement each-other, personally. Maya is great for parsing websites, and dealing with calendar events!

☤ Installing Maya

Installation is easy, with pipenv:

$ pipenv install maya
