Add months to the current date in Python

Add months to the current date in Python #

To add months to the current date in Python:

1. Use the datetime.now() method to get the current local date and time.
2. Create a relativedelta object by passing the number of months to the relativedelta class.
3. Sum the current date and the relativedelta object.

from datetime import datetime
from dateutil.relativedelta import relativedelta

now = datetime.now()
print(now)  # 👉️ 2022-06-22 19:27:37.483564

result = now + relativedelta(months=+3)

print(result)  # 👉️ 2022-09-22 19:27:37.483564

We used the datetime.now method to get the current local date and time.

Make sure to import the relativedelta and the datetime classes.

pip install python-dateutil

Notice that we prefixed the number of months with a plus + to indicate that we want to add the specified number of months.

If necessary, the year will be rolled over automatically (e.g. adding 6 months to a date in September).

If you only need to extract the date after the operation, call the date() method on the datetime object.

from datetime import datetime
from dateutil.relativedelta import relativedelta

now = datetime.now()
print(now)  # 👉️ 2022-06-22 19:27:37.483564

result = now + relativedelta(months=+3)

print(result)  # 👉️ 2022-09-22 19:27:37.483564

# 👇️ only extract updated date
print(result.date())  # 👉️ 2022-09-22

The datetime.date method returns a date object with the same year, month and day.

If you need to format the date in a certain way, use a formatted string literal.

from datetime import datetime
from dateutil.relativedelta import relativedelta

now = datetime.now()
print(now)  # 👉️ 2022-06-22 19:34:48.991786

result = now + relativedelta(months=+5)

print(result)  # 👉️ 2022-11-22 19:34:48.991786

# 👇️ only extract updated date
print(result.date())  # 👉️ 2022-11-22

print(f'{result:%Y-%m-%d %H:%M:%S}')  # 👉️ 2022-11-22 19:34:48

Formatted string literals (f-strings) let us include expressions inside of a string by prefixing the string with f.

Make sure to wrap expressions in curly braces - {expression}.

Formatted string literals also enable us to use the format specific mini-language in expression blocks.
