Overview
The Standard Library datetime
module provides datetime
, date
and time
types. The datetime
type combines information stored in data
and time
and it is the most commonly used. Additionally, the dateutil
module provides useful extensions.

Sleep
from time import sleep
sleep(1)

datetime Overview
The datetime
module provides classes for manipulating dates and times.
https://docs.python.org/3/library/datetime.html#module-datetime
The datetime
package documentation seems to recommend the dateutil
for time zone support and parsing.
The datetime.datetime Type
Time Interval with timedelta
from datetime import datetime
dt1 = datetime.datetime(2022,3,27,13,27,45,46000)
dt2 = datetime.datetime(2022,6,30,14,28)
tdelta = dt2 - dt1
print(tdelta)
print(type(tdelta))
To get the total number of seconds in timedelta
, use total_seconds()
:
from datetime import datetime
t0 = datetime.now()
...
t1 = datetime.now()
print((t1 - t0).total_seconds())
now Time
from datetime import datetime
now = datetime.now()
current_time = now.strftime("%H:%M:%S")
print("Current Time =", current_time)
Current Date
With now()
:
from datetime import datetime
d = datetime.now().strftime("%Y-%m-%d")
print(d) # displays YYYY-mm-dd
With date.today()
:
from datetime import date
print(str(date.today())) # displays YYYY-mm-dd
Format
from datetime import datetime
s = '12/31/2023'
d = datetime.strptime(s, "%m/%d/%Y")
assert d.year == 2023
assert d.month == 12
assert d.day == 31
The common timestamp elements are '%Y-%m-%d %H:%M:%S'. For more details on date format, see ?
Also see Time, Date and Timestamp Parsing with dateutil below.
dateutil Module
Time, Date and Timestamp Parsing with dateutil
The datetime
package documentation seems to recommend the dateutil
for time zone support and parsing.
import dateutil.parser as du
d = du.parse('10/01/2023')
assert d.year == 2023
assert d.month == 10
assert d.day == 1
