Python Current Date Time

We can use Python datetime module to get the current date and time of the local system.

Copy
from datetime import datetime

# Current date time in local system
print(datetime.now())

Output: 2018-09-12 14:17:56.456080

Python Current Date

If you are interested only in the date of the local system, you can use the datetime date() method.

Copy
print(datetime.date(datetime.now()))

Output: 2018-09-12

Python Current Time

If you want only time in the local system, use time() method by passing datetime object as an argument.

Copy
print(datetime.time(datetime.now()))

Output: 14:19:46.423440

Python Current Date Time in timezone – pytz

Most of the times, we want the date in a specific timezone so that it can be used by others too. Python datetime now() function accepts timezone argument that should be an implementation of tzinfo abstract base class.

Python pytz is one of the popular module that can be used to get the timezone implementations.

You can install this module using the following PIP command.

Copy
pip install pytz

Let’s look at some examples of using pytz module to get time in specific timezones.

Copy
import pytz

utc = pytz.utc
pst = pytz.timezone('America/Los_Angeles')
ist = pytz.timezone('Asia/Calcutta')

print('Current Date Time in UTC =', datetime.now(tz=utc))
print('Current Date Time in PST =', datetime.now(pst))
print('Current Date Time in IST =', datetime.now(ist))

Output:

Copy
Current Date Time in UTC = 2018-09-12 08:57:18.110068+00:00
Current Date Time in PST = 2018-09-12 01:57:18.110106-07:00
Current Date Time in IST = 2018-09-12 14:27:18.110139+05:30

If you want to know all the supported timezone strings, you can print this information using the following command.

Copy
print(pytz.all_timezones)

It will print the list of all the supported timezones by the pytz module.

Python Pendulum Module

Python Pendulum module is another timezone library and according to its documentation, it is faster than the pytz module.

We can install Pendulum module using below PIP command.

Copy
pip install pendulum

You can get list of supported timezone strings from pendulum.timezones attribute.

Let’s look into some examples of getting current date and time information in different time zones using the pendulum module.

Copy
import pendulum

utc = pendulum.timezone('UTC')
pst = pendulum.timezone('America/Los_Angeles')
ist = pendulum.timezone('Asia/Calcutta')

print('Current Date Time in UTC =', datetime.now(utc))
print('Current Date Time in PST =', datetime.now(pst))
print('Current Date Time in IST =', datetime.now(ist))

Output:

Copy
Current Date Time in UTC = 2018-09-12 09:07:20.267774+00:00
Current Date Time in PST = 2018-09-12 02:07:20.267806-07:00
Current Date Time in IST = 2018-09-12 14:37:20.267858+05:30
