Convert a String to DateTime in Python
Let us see, how to convert a string into datetime in python.
In this example, I have imported a module called datetime.
Example:
To get the output we will print((datetime.datetime.now())). You can refer to the below screenshot for the output:
How to convert a string to datetime object in Python
Let us see, how to convert a string into datetime object in python.
- In this example, I have imported a module called datetime, passed a variable as dt_string = '2020-12-18 3:11:09', and assigned format = '%Y-%m-%d %H:%M:%S' .
- I have used strptime string. This string represents a time according to format.
- dt_object = datetime.datetime.strptime(dt_string, format) used to create datetime object.
In the code above, The now method from the datetime class returns the current local date and time.Hence, at this point, dt holds the datetime object containing the date and time information Nextly, we use the strftime method to convert the dt (datetime object) into a formattable string; Finally, we print the current date and time in our desired manner.
Example:
To get the output as datetime object print('Datetime: ', dt_object), to get minute object print('Minute: ', dt_object.minute), to get hour object print('Hour: ', dt_object.hour) and, to get second object print('Second: ', dt_object.second).
You can refer below screenshot for the output:
Convert a string to datetime pandas in Python
Now, we can see how to convert a string to datetime pandas in python.
In this example, I have a module called pandas. Pandas is a library that is used for data science. Here, we will import pandas as pd. The pd.to_datetime(dt) method is used to convert the string datetime into a datetime object using pandas in python.
Example:
To get the output as datetime object print(pd.to_datetime(dt)) is used.
You can refer the below screenshot for the output:
Python convert a string to datetime with timezone
Now, we can see how to convert a string to datetime with timezone in python.
In this example, I have imported a module called timezone. datetime.now(timezone(‘UTC')) is used to get the present time with timezone. The format is assigned as time = '%Y-%m-%d %H:%M:%S%Z%z'. The %z is used to get timezone along with datetime.
Example:
To get the output print(‘UTC :', time) is used. In the below screenshot, we can see the output.
Python convert a string to datetime with milliseconds
Let us see how to convert a string to datetime with milliseconds in python.
In this example, I have imported a module called datetime. The dt = datetime.datetime.now() is used to get the present time. Here, %f is used to get time with milliseconds.
Example:
To get the output as datetime with milliseconds print(dt). You can refer to the below screenshot for the output:
Python converting a string to datetime without format
Now we can see, how to convert string to datetime without format in python.
In this example, I have imported a module called a parser. The parser function will parse a string automatically in the dt variable. dateutil module is the extension for the standard datetime module. The datetime string is passed without format.
Example:
To get the final result print(dt) is used. Below screenshot shows the output:
Python converting a string to datetime iso format
Here, we can see how to converting a string to datetime iso format in python
In this example, I have imported a module called datetime and used .isoformat to convert present time into iso format.
Example:
To get the output in iso format, here I have used print(dt.isoformat()). You can see the below screenshot for output:
Python convert a string to datetime yyyy-mm-dd
Now we can see, how to convert a string to datetime yyyy-mm-dd in python.
- In this example, I have imported a module called datetime. And assigned input as '2020-12-21' to the variable as dt_string, and the format as format = '%Y-%m-%d'.
- strptime is a string that represents a time according to format.
- dt_object = datetime.datetime.strptime(dt_string, format) In this two arguments are passed one is dt_string and other one is format.
Example:
To get the output print(dt_object) is used in this example. You can refer to the below screenshot for the output:
How to convert a string to timestamp in Python
Here, we can see how to convert a string into timestamp in Python.
In this example, I have imported a module called datetime and assigned an input string as a date and the strptime string is used to get the time in the format. Timestamp() is a function that returns the time in the form of seconds.
Example:
To get the output print(ts) is used. In the below screenshot, you can see the output in which the time is in the form of seconds.
Python converting a string to datetime.date
- Here, we can see how to convert a string to datetime.date in python.
- In this example, I have imported a module called datetime and passed an input string as ‘2020/12/21'
- To get only get date format as the output, we have to manually divide and pass the split string for the input string. And convert it by using int datatype, and also assign the index values for the input string.
- Get Current Date and Time. Import datetime datetimeobject = datetime.datetime.now.
- From datetime import datetime datetime.utcnow.strftime ('%Y%m%d') I prefer the first approach, as it gets you in the habit of using timezone aware datetimes - but as J.F. Sebastian pointed out - it requires Python 3.2+. The second approach will work in both 2.7 and 3.2 branches.
- Converting the date object first to datetime also does not help. I tried the example at this link from, but: from pytz import utc, timezone from datetime import datetime from time import mktime inputdate = datetime (year = 2011, month = 1, day = 15) and now either: mktime (utc.

How to convert a string to datetime UTC in Python
Here, we can see how to convert a string to datetime utc format in Python.
- In this example, I have imported modules called pytz and datetime. And assigned timezone as pytz.timezone ('Asia/Kolkata').
- Pytz is a library used for timezone calculation and lc.localize() is used to make a naive timezone. A simple datetime object is called a timezone naive, and lc_datetime.astimezone() is a function used to set the time according to the required timezone.
Example:
To get the output as time in UTC format print(utc_date_time), and it will return date and time. You can refer to the below screenshot for the output.

Question or problem about Python programming:
I am dealing with dates in Python and I need to convert them to UTC timestamps to be used
inside Javascript. The following code does not work:
Converting the date object first to datetime also does not help. I tried the example at this link from, but:
Datetime Format Python
and now either:
or
does work.
So general question: how can I get a date converted to seconds since epoch according to UTC?
How to solve the problem:
Solution 1:
If d = date(2011, 1, 1) is in UTC:
If d is in local timezone:
timestamp1 and timestamp2 may differ if midnight in the local timezone is not the same time instance as midnight in UTC.
mktime() may return a wrong result if d corresponds to an ambiguous local time (e.g., during DST transition) or if d is a past(future) date when the utc offset might have been different and the C mktime() has no access to the tz database on the given platform. You could use pytz module (e.g., via tzlocal.get_localzone()) to get access to the tz database on all platforms. Also, utcfromtimestamp() may fail and mktime() may return non-POSIX timestamp if 'right' timezone is used.
To convert datetime.date object that represents date in UTC without calendar.timegm():
How can I get a date converted to seconds since epoch according to UTC?
To convert datetime.datetime (not datetime.date) object that already represents time in UTC to the corresponding POSIX timestamp (a float).
datetime.timestamp():
Note: It is necessary to supply timezone.utc explicitly otherwise .timestamp() assume that your naive datetime object is in local timezone.
From the docs for datetime.utcfromtimestamp():
There is no method to obtain the timestamp from a datetime instance,
but POSIX timestamp corresponding to a datetime instance dt can be
easily calculated as follows. For a naive dt:
And for an aware dt:
Python Datetime From Utc Timestamp
Interesting read: Epoch time vs. time of day on the difference between What time is it? and How many seconds have elapsed?
See also: datetime needs an 'epoch' method
Python 2To adapt the above code for Python 2:
where timedelta.total_seconds() is equivalent to (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6 computed with true division enabled.
Haworth very wire stacker. Beware of floating-point issues.

On Python 2:
Solution 2:
For unix systems only:
Note 1: dizzyf observed that this applies localized timezones. Don't use in production.
Note 2: Jakub Narębski noted that this ignores timezone information even for offset-aware datetime (tested for Python 2.7).
Solution 3:
Python Datetime From Utc String
Assumption 1: You're attempting to convert a date to a timestamp, however since a date covers a 24 hour period, there isn't a single timestamp that represents that date. I'll assume that you want to represent the timestamp of that date at midnight (00:00:00.000).
Assumption 2: The date you present is not associated with a particular time zone, however you want to determine the offset from a particular time zone (UTC). Without knowing the time zone the date is in, it isn't possible to calculate a timestamp for a specific time zone. I'll assume that you want to treat the date as if it is in the local system time zone.
First, you can convert the date instance into a tuple representing the various time components using the timetuple() member:
You can then convert that into a timestamp using time.mktime:
You can verify this method by testing it with the epoch time itself (1970-01-01), in which case the function should return the timezone offset for the local time zone on that date:
Python Datetime Module
28800.0 is 8 hours, which would be correct for the Pacific time zone (where I'm at).
Solution 4:
Utc est cst pst cet. I defined my own two functions
- utc_time2datetime(utc_time, tz=None)
- datetime2utc_time(datetime)
Utc Time Datetime Python
here:
Solution 5:
follow the python2.7 document, you have to use calendar.timegm() instead of time.mktime()
Hope this helps!
