In this article, we will discuss the addition of time onto a specified DateTime object in Python. The effect of this will produce a new DateTime object. This addition can be performed by usingdatetime.timedelta[] function. The timedelta[] function is used for calculating differences in dates and also can be used for date manipulations in Python. It is one of the easiest ways to perform date manipulations.
Syntax: datetime.timedelta[days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0]
Return values: This function returns the manipulated date.
Thus by simply passing an appropriate value to the above-given parameters, the required task can be achieved.
Example 1: Adding time to DateTime object
Python3
import
datetime
date_and_time
=
datetime.datetime[
2021
,
8
,
22
,
11
,
2
,
5
]
print
[
"Original time:"
]
print
[date_and_time]
time_change
=
datetime.timedelta[minutes
=
75
]
new_time
=
date_and_time
+
time_change
print
[
"changed time:"
]
print
[new_time]
Output:
Original time: 2021-08-22 11:02:05 changed time: 2021-08-22 12:17:05
Example 2: Changing day by adding time to DateTime
Python3
import
datetime
date_and_time
=
datetime.datetime[
2021
,
8
,
22
,
11
,
2
,
5
]
print
[
"Original time:"
]
print
[date_and_time]
time_change
=
datetime.timedelta[hours
=
36
]
new_time
=
date_and_time
+
time_change
print
[
"changed time:"
]
print
[new_time]
Output:
Original time: 2021-08-22 11:02:05 changed time: 2021-08-23 23:02:05
Example 3: Changing two parameters at the same time
Python3
import
datetime
date_and_time
=
datetime.datetime[
2021
,
8
,
22
,
11
,
2
,
5
]
print
[
"Original time:"
]
print
[date_and_time]
time_change
=
datetime.timedelta[minutes
=
2
, seconds
=
10
]
new_time
=
date_and_time
+
time_change
print
[
"changed time:"
]
print
[new_time]
Output:
Original time: 2021-08-22 11:02:05 changed time: 2021-08-22 11:04:15
Prerequisites: Datetime module
Every minute should be enjoyed and savored. Time is measured by the hours, days, years, and so on. Time helps us to make a good habit of organizing and structuring our daily activities. In this article, we will see how we can extract real-time from a python module. There are various ways to pass the date and time feature to the program. Python ‘Time’ and ‘Calendar’ module help in tracking date and time. Also, the ‘DateTime’ provides a class for controlling date and time in both simple and complex ways. So with the help of this module, we will try to figure out our future desire time by adding hours in real-time with the help of ‘timedelta[ ]’.
To get both current date and time datetime.now[] function of DateTime module is used. This function returns the current local date and time.
Syntax : datetime.now[tz]
Parameters : tz : Specified time zone of which current time and date is required. [Uses Greenwich Meridian time by default.]
Returns : Returns the current date and time in time format.
Approach :
- Import DateTime module.
- Display Current time.
- Create a new variable to Updated time.
- Store the Updated time in that variable.
- Display Updated Time.
Implementation :
Step 1: Showing current time.
Firstly, we will Import ‘datetime’ and ‘timedelta’ from datetime module, Then we will store our Present time in a variable. After that, we will align date in “HH:MM:SS” format. Now we can print our Present time.
Python3
from
datetime
import
datetime, timedelta
present_time
=
datetime.now[]
'{:%H:%M:%S}'
.
format
[present_time]
print
[
"Present time at greenwich meridian is "
,end
=
""]
print
[ present_time ]
Output:
Present time at greenwich meridian is 2020-11-11 08:26:55.032586
Step 2: Adding the time to the existing current time.
After the following above steps, we will pass the desired time in ‘timedelta’ function that will add hour in present time.
Now, we can display updated time.
Python3
from
datetime
import
datetime, timedelta
present_time
=
datetime.now[]
'{:%H:%M:%S}'
.
format
[ present_time ]
print
[
"Present time at greenwich meridian is "
,
end
=
""]
print
[ present_time ]
updated_time
=
datetime.now[]
+
timedelta[hours
=
6
]
print
[ updated_time ]
Output:
Present time at greenwich meridian is 2020-11-11 08:27:39.615794
2020-11-11 14:27:39.615794
Another better way you can try :
Python3
from
datetime
import
datetime, timedelta
updated
=
[ datetime.now[]
+
timedelta[ hours
=
5
]].strftime[
'%H:%M:%S'
]
print
[ updated ]
Output:
13:28:21
