Python datetime.tzname() Method

datetime.tzname() method is used in the datetime class of module datetime.

It uses an instance of the class and returns the time zone name of the datetime object passed, as a string. It is an instance method and works on an aware object. For a naive object, it returns None.

Module:

    import datetime

Class:

    from datetime import datetime

Syntax:

    tzname()

Parameter(s):

• None

Return value:

Returns the time zone name of the datetime object passed, as a string.

Example:

from datetime import datetime
import pytz

naive= datetime.now()
## Tzinfo is missing from the time object 
## which is naive 
print(naive)
print(naive.tzinfo)
print("Timezone for a naive object:", naive.tzname())
print()

## Adding a timezone
timezone = pytz.timezone("Asia/Kolkata")
aware1 = timezone.localize(naive)
print(aware1)
print("Tzinfo:",aware1.tzinfo)
print("Timezone name:", aware1.tzname())
print()

## After adding the timezone info, 
## the object it becomes aware
timezone = pytz.timezone("Asia/Tokyo")
aware2 = timezone.localize(naive)
print("Tzinfo:",aware2.tzinfo)
print("Timezone name:", aware2.tzname())
print()

timezone = pytz.timezone("America/New_York")
aware3 = timezone.localize(naive)
print("Tzinfo:",aware3.tzinfo)
## timedelta comes as -1 day 20 hrs 
## which is equal to -4 hrs 
print("Timezone name:", aware3.tzname())
print()

## You can also use the astimezone function
## of  datetime to 
timezone = pytz.timezone("Europe/Berlin")
aware4 = naive.astimezone(timezone)
print("Tzinfo:",aware4.tzinfo)
print("Timezone name:", aware4.tzname())

Output

2020-04-30 20:20:30.748312
None
Timezone for a naive object: None

2020-04-30 20:20:30.748312+05:30

Timezone name: IST

Tzinfo: Asia/Tokyo
Timezone name: JST
