Python Date and Time: Python can handle date and time in several ways. The calendar modules and time help track dates and times.
How To Get Python Date & Time?
Time intervals are floating-point numbers in units of seconds. Particular instants in time are expressed in seconds since 12:00 am, January 1, 1970 (epoch).
There is a popular time module available in Python which provides functions for working with times, and for converting between representations. The function time.time() returns the current system time in ticks since 12:00am, January 1, 1970(epoch).
import time; # This is required to include a time module. ticks = time.time() print "Number of ticks since 12:00am, January 1, 1970:", ticks
Number of ticks since 12:00 am, January 1, 1970: 7186862.73399
Python function handles time as a tuple of 9 numbers. check here as follows:
|1||Month||1 to 12|
|2||Day||1 to 31|
|3||Hour||0 to 23|
|4||Minute||0 to 59|
|5||Second||0 to 61 (60 or 61 are leap-seconds)|
|6||Day of Week||0 to 6 (0 is Monday)|
|7||Day of year||1 to 366 (Julian day)|
|8||Daylight savings||-1, 0, 1, -1 means library determines DST|
|1||tm_mon||1 to 12|
|2||tm_mday||1 to 31|
|3||tm_hour||0 to 23|
|4||tm_min||0 to 59|
|5||tm_sec||0 to 61 (60 or 61 are leap-seconds)|
|6||tm_wday||0 to 6 (0 is Monday)|
|7||tm_yday||1 to 366 (Julian day)|
|8||tm_isdst||-1, 0, 1, -1 means library determines DST|
Get Current Time
If you want to get instant time from seconds, while the epoch floating point value into a time tuple, pass floating point value to a function. (i.e local time)
import time; local time = time.localtime(time.time()) print "Local current time:", localtime
Local current time: time.struct_time(tm_year=2019, tm_mon=1,tm_mday=1, tm_hour=01, tm_min=20, tm_sec=3, tm_wday=2, tm_yday=198, tm_isdst=0)
Get formatted time
You can format any time as per your requirement. You can do it by asctime( )
import time; localtime = time.asctime( time.localtime(time.time()) ) print "Local current time:", localtime
Local current time: Tue Jan 13 10:17:09 2009
Get Calendar of Month
If you want to get a calendar of the month.
import calendar Cal = calendar.month(2008, 1) print "Here is the calendar:" print cal
Here is the calendar:
Mo Tu We Th Fr Sa Su
1 2 3 4 5 6
7 8 9 10 11 12 13
14 15 16 17 18 19 20
21 22 23 24 25 26 27
28 29 30 31
Get date from a timestamp
We can also create date objects from a timestamp. A Unix timestamp is the number of seconds between a particular date and January 1, 1970, at UTC. And we can convert a timestamp to date using from timestamp() method.
from datetime import date timestamp = date.fromtimestamp(1326244364) print("Date =", timestamp)
Date = 2012-01-11
Print today’s year, month and day
from datetime import date #date object of today's date today = date.today() print("Current year:", today.year) print("Current month:", today.month) print("Current day:", today.day)
Current year: 2019
Current month: 5
Current day: 25
The datetime module has a class named dateclass that can contain information from both date and time objects.
from datetime import datetime #datetime(year, month, day) a = datetime(2019, 11, 28) print(a) # datetime(year, month, day, hour, minute, second, microsecond) b = datetime(2010, 5, 28, 23, 55, 59, 342380) print(b)
Handling timezone in Python
If you need to display date and time based on their timezone. Rather than trying to handle timezone yourself, we suggest you use a third-party pytZ module.
from datetime import datetime import pytz local = datetime.now() print("Local:", local.strftime("%m/%d/%Y, %H:%M:%S")) tz_NY = pytz.timezone('America/New_York') datetime_NY = datetime.now(tz_NY) print("NY:", datetime_NY.strftime("%m/%d/%Y, %H:%M:%S")) tz_London = pytz.timezone('Europe/London') datetime_London = datetime.now(tz_London) print("London:", datetime_London.strftime("%m/%d/%Y, %H:%M:%S"))
Local time: 2018-12-20 13:10:44.260462
America/New_York time: 2018-12-20 13:10:44.260462
Europe/London time: 2018-12-20 13:10:44.260462
