khayyam.JalaliDatetime(989, 3, 25, 10, 43, 23, 345453, Seshanbeh)

Current date and time

>>> print(JalaliDatetime.now())
khayyam.JalaliDatetime(1394, 5, 18, 16, 4, 48, 628383, Yekshanbeh)

>>> print(JalaliDatetime.now(TehranTimezone()) - timedelta(days=6*30))
1393-11-02 20:01:11.663719+03:30

>>> print(JalaliDate.today())
1394-4-30

>>> JalaliDatetime.strptime(u'چهارشنبه ۳۱ تیر ۱۳۹۴ ۰۵:۴۵:۴۰ ب.ظ', '%C')
khayyam.JalaliDatetime(1394, 4, 31, 17, 45, 40, 0, Chaharshanbeh)

Converting

>>> from datetime import date, datetime
>>> JalaliDate(1394, 4, 31).todate()
datetime.date(2015, 7, 22)

>>> now = JalaliDatetime(1394, 4, 31, 15, 38, 6, 37269)
>>> now.todate()
datetime.date(2015, 7, 22)

>>> now.todatetime()
datetime.datetime(2015, 7, 22, 15, 38, 6, 37269)

>>> JalaliDatetime(datetime(2015, 7, 22, 14, 47, 9, 821830))
khayyam.JalaliDatetime(1394, 4, 31, 14, 47, 9, 821830, Chaharshanbeh)

>>> JalaliDatetime(datetime(2015, 7, 22, 14, 47, 9, 821830, TehranTimezone()))
khayyam.JalaliDatetime(1394, 4, 31, 14, 47, 9, 821830, tzinfo=+03:30 dst:60, Chaharshanbeh)

>>> JalaliDate(date(2015, 7, 22))
khayyam.JalaliDate(1394, 4, 31, Chaharshanbeh)

Arithmetics & Operators

>>> from datetime import timedelta
>>> from khayyam import JalaliDate, JalaliDatetime
>>> now = JalaliDatetime(1394, 4, 31, 16, 17, 31, 374398)
>>> now + timedelta(days=1)
khayyam.JalaliDatetime(1394, 5, 1, 16, 17, 31, 374398, Panjshanbeh)

>>> now + timedelta(seconds=3600)
khayyam.JalaliDatetime(1394, 4, 31, 17, 17, 31, 374398, Chaharshanbeh)

>>> now - timedelta(seconds=3600)
khayyam.JalaliDatetime(1394, 4, 31, 15, 17, 31, 374398, Chaharshanbeh)

>>> yesterday = now - timedelta(1)
>>> yesterday
khayyam.JalaliDatetime(1394, 4, 30, 16, 17, 31, 374398, Seshanbeh)

>>> now - yesterday
datetime.timedelta(1)

>>> JalaliDatetime.now() - now
datetime.timedelta(0, 478, 328833) # 478 seconds taken to writing this section

Comparison

>>> now > yesterday
True

>>> now != yesterday
True

>>> now.todate() == yesterday.todate()
False
