timedelta(): represents a duration, or the difference between two dates or times

Importing datetime library

from datetime import timedelta

from datetime import date,datetime,timedelta
dt=date.today()
print("Today:",dt)
dt2=dt + timedelta(days=5) # 5 days 
print("New Date: ",dt2)

Today: 2019-09-19
New Date:  2019-09-24

Adding day and hours

from datetime import timedelta,date,datetime
dt=datetime.now()
dt2=dt + timedelta(days=5,hours=3)
print(dt2)

2019-09-24 20:22:25.828862

Adding all options to present date and time

from datetime import timedelta,date,datetime
dt=datetime.now()
dt2=dt + timedelta(days=5,weeks=2,hours=3,minutes=5,seconds=4,microseconds=0.000001,milliseconds=123)
print(dt2)

2019-10-07 11:22:38.468063

from datetime import timedelta,date,datetime
dt=datetime.now()
dt2=dt + timedelta(days=5)
dt3=dt + timedelta(days=4)
print(dt2-dt3)

1 day, 0:00:00

from datetime import timedelta,date,datetime
month_delta=timedelta(days=-30)
dt=date.today()
print(dt+month_delta)

2019-08-20

year_delta=timedelta(days=365)
dt=date.today()
print(dt+year_delta)

2020-09-18

import datetime
from datetime import timedelta
dt1=datetime.datetime(2018,3,1)
dt2=datetime.datetime(2019,3,1)
year_delta=timedelta(days=365)
print(dt1+year_delta)
print(dt2+year_delta)

2019-03-01 00:00:00
2020-02-29 00:00:00

total_seconds()

from datetime import timedelta,date,datetime
month_delta=timedelta(days=30)
print(month_delta.total_seconds())

2592000.0

resolution

print(month_delta.resolution)

0:00:00.000001
