Add minutes to datetime in Python #
Use the timedelta() class from the datetime module to add minutes to
datetime, e.g. result = dt + timedelta(minutes=10). The timedelta class can
be passed a minutes argument and adds the specified number of minutes to the
datetime.
from datetime import datetime, timedelta # ✅ parse datetime string and add minutes to datetime d = '2023-11-24 09:30:00.000123' # 👇️ convert string to datetime object dt = datetime.strptime(d, '%Y-%m-%d %H:%M:%S.%f') print(dt) # 👉️ 2023-11-24 09:30:00.000123 result_1 = dt + timedelta(minutes=29) print(result_1) # 👉️ 2023-11-24 09:59:00.000123 # ----------------------- # ✅ add minutes to datetime dt_2 = datetime(2023, 9, 24, 9, 30, 35) print(dt_2) # 👉️ 2023-09-24 09:30:35 result_2 = dt_2 + timedelta(minutes=15) print(result_2) # 👉️ 2023-09-24 09:45:35 # ------------------------ # ✅ add minutes to current time now = datetime.today() print(now) # 👉️ 2022-06-22 12:35:30.302272 result_3 = now + timedelta(minutes=5) print(result_3) # 👉️ 2022-06-22 12:40:30.302272
09:30:13 scroll down to the last code snippet.Make sure to import the datetime and
timedelta
classes from the datetime module.
The first example creates a datetime object from a datetime string and adds
minutes to it.
from datetime import datetime, timedelta # ✅ parse datetime string and add minutes to datetime d = '2023-11-24 09:30:00.000123' # 👇️ convert string to datetime object dt = datetime.strptime(d, '%Y-%m-%d %H:%M:%S.%f') print(dt) # 👉️ 2023-11-24 09:30:00.000123 result_1 = dt + timedelta(minutes=29) print(result_1) # 👉️ 2023-11-24 09:59:00.000123
The datetime.strptime() method returns a datetime object that corresponds to the provided date string, parsed according to the format.
If you have a date string that is formatted in a different way, use
this table of the docs
to look up the format codes you should pass as the second argument to the
strptime() method.
The second example uses the
datetime
class to create a datetime object and the timedelta class to add minutes to
it.
from datetime import datetime, timedelta dt_2 = datetime(2023, 9, 24, 9, 30, 35) print(dt_2) # 👉️ 2023-09-24 09:30:35 result_2 = dt_2 + timedelta(minutes=15) print(result_2) # 👉️ 2023-09-24 09:45:35
We passed values for the year, month, day, hour, minute and second
arguments.
The third example adds minutes to the current time.
from datetime import datetime, timedelta now = datetime.today() print(now) # 👉️ 2022-06-22 12:35:30.302272 result_3 = now + timedelta(minutes=5) print(result_3) # 👉️ 2022-06-22 12:40:30.302272
The datetime.today() method returns the current local datetime.
datetime object because it automatically rolls over the hours, days, months and years if necessary.This wouldn't be possible if we only had the time component. For example,
11:59:30PM + 15 minutes would raise an exception.
datetime.combine method to combine the time with the current (or some other) date and get a datetime object.from datetime import datetime, date, timedelta, time t = time(9, 25) print(t) # 👉️ 09:25:00 result = datetime.combine(date.today(), t) + timedelta(minutes=30) print(result) # 👉️ 2022-06-22 09:55:00 only_t = result.time() print(only_t) # 👉️ 09:55:00
The
datetime.combine
method takes a date and time as arguments and returns a new datetime
object by combining them.
Once we get a datetime object, we can use the timedelta class to add minutes
to it.
Use the time() method on the datetime object if you only need to extract the
time after the operation.
from datetime import datetime, date, timedelta, time t = time(9, 25) print(t) # 👉️ 09:25:00 result = datetime.combine(date.today(), t) + timedelta(minutes=30) print(result) # 👉️ 2022-06-22 09:55:00 # ✅ only get updated time only_t = result.time() print(only_t) # 👉️ 09:55:00
The datetime.time method returns a time object with the same hour, minute, second and millisecond.
