In this article, you will learn to convert timestamp to datetime object and datetime object to timestamp [with the help of examples].
It's pretty common to store date and time as a timestamp in a database. A Unix timestamp is the number of seconds between a particular date and January 1, 1970 at UTC.
Example 1: Python timestamp to datetime
from datetime import datetime
timestamp = 1545730073
dt_object = datetime.fromtimestamp[timestamp]
print["dt_object =", dt_object]
print["type[dt_object] =", type[dt_object]]
When you run the program, the output will be:
dt_object = 2018-12-25 09:27:53 type[dt_object] =
Here, we have imported datetime class from the datetime module. Then, we used datetime.fromtimestamp[] classmethod which returns the local date and time [datetime object]. This object is stored in dt_object variable.
Note: You can easily create a string representing date and time from a datetime object using
strftime[] method.
Example 2: Python datetime to timestamp
You can get timestamp from a datetime object using datetime.timestamp[] method.
from datetime import datetime
# current date and time
now = datetime.now[]
timestamp = datetime.timestamp[now]
print["timestamp =", timestamp]
from datetime import datetime
from time import time
print[f'{datetime.now[]} and {time[]}']
Yield 2022-03-25 16:27:37.051854 and 1648193257.051854
I hope to getdatetime.now[] from time[].
I found Sec: 37 = 1648193257 % 60.
27469887 = 1648193257 // 60
min: 27 = 27469887 % 60
But I could not find how can yield hour data and so on.

You can use the datetime.datetime.fromtimestamp[] function for it.
print[datetime.datetime.now[]]
now = time.time[]
print[now]
print[datetime.datetime.fromtimestamp[now]]
Yields
2022-03-25 09:13:42.665469
1648196022.6654692
2022-03-25 09:13:42.665469

I recommend that you review this documentation
As an example, you can get the current hour as follows:
import time
print[time.localtime[].tm_hour]

In this article, we will discuss how to convert a date to a datetime object in python.
We use the combine method from the datetime module to combine a date and time object to create a datetime object.
Syntax
The syntax of combine[] method is as follows.
datetime.combine[date,time]
Where,
- date is a date object.
- time is a time object.
This method returns a datetime object which is the combination of the above two objects[date,time].
Converting a date object to datetime object
If we have a date object and don't have a time object, then you initialize the time object to a minimum using the datetime object [Minimum means at midnight i.e 00:00:00].
Example
In the below example code, we combine a date object is retrieved by using the today[] method and we initialized the time object to minimum time[00:00:00] using the min.time[] method. And combined these two objects by applying the datetime.combine[] method.
from datetime import date from datetime import datetime my_date = date.today[] print["The date object:",my_date] my_time = datetime.min.time[] print["The time object:",my_time] my_datetime = datetime.combine[my_date, my_time] print["The combined datetime object:",my_datetime]
Output
The output of the above code is as follows.
The date object: 2022-05-19 The time object: 00:00:00 The combined datetime object: 2022-05-19 00:00:00
When both date and time objects are given
Here, we initialize both date and time objects. And combine these into a datetime object using the combine method.
Example
In this example, we will convert a datetime object when both date and time objects are given.
import datetime my_date = datetime.datetime[2012, 2, 12] print["The date object:",my_date] my_time = datetime.time[1, 30] print["The time object:",my_time] combined_datetime = my_date.combine[my_date, my_time] print["The combined datetime object:",combined_datetime]
Output
The output of the above code is as follows;
The date object: 2012-02-12 00:00:00 The time object: 01:30:00 The combined datetime object: 2012-02-12 01:30:00
Using the datetime[]
The datetime[] constructor in python accepts year, month and date values as parameters and create a datetime object.
Pass the year, month and day values of the desired date object [as my_date.year, my_date.month, my_date.day] to this constructor to convert a date object to datetime object.
Example
from datetime import date from datetime import datetime my_date = date.today[] my_datetime = datetime[my_date.year, my_date.month, my_date.day] print[my_datetime]
Output
2022-09-05 00:00:00
