Python Extract Year from Date

Extracting year from date is a common task that helps you to analyze the data in some ways.

In this tutorial, I will show you different cases of extracting year from date in Python. Keep reading to see which way fits your case.

For your reference:

• Extract Year from String Date: "2023-11-03" ⟶ 2023.
• Extract Year from Date Object: datetime(2023, 11, 3) ⟶ 2023.
• Extract Year from Timestamp: 1699006871 ⟶ 2023.
• Extract Current Year: datetime.now() ⟶ 2023.

Extract Year from String Date

If you have a string date, e.g. "2023-11-03", you can use the datetime.strptime() method to extract the year from it: datetime.strptime(date, "%Y-%m-%d").year.

This can be done in two steps:

1. Convert the string into a datetime object using the strptime method.
2. Use the year attribute to get the year.

Example:

from datetime import datetime

date = "2023-11-03"
year = datetime.strptime(date, "%Y-%m-%d").year

print(year)
# 2023

More complex examples:

from datetime import datetime

date = "2023-11-03 17:23:00"
year = datetime.strptime(date, "%Y-%m-%d %H:%M:%S").year

print(year)
# 2023

The patterns such as %Y, %m, etc. can be found in the Python documentation.

Extract Year from Date Object

If you have a datetime object, you can use the year attribute to get the year: datetime(2023, 11, 3).year.

from datetime import datetime

date = datetime(2023, 11, 3)
year = date.year

print(date)
# 2023-11-03 00:00:00
print(year)
# 2023

Extract Year from Timestamp

For a timestamp, you can use the fromtimestamp method to convert it into a datetime object, then use the year attribute to get the year: datetime.fromtimestamp(timestamp).year.

from datetime import datetime

timestamp = 1699006871
date = datetime.fromtimestamp(timestamp)
year = date.year

print(date)
# 2023-11-03 17:21:11
print(year)
# 2023

17:21:11 is the time I wrote this tutorial.

Extract Current Year

To get the current year, you can use the datetime module with the now method: datetime.now().year.

from datetime import datetime

year = datetime.now().year

print(year)
# 2023

Conclusion

To extract year from date in Python, you can use the following methods:

• datetime.strptime(date, "%Y-%m-%d").year
• datetime.strptime(date, "%Y-%m-%d %H:%M:%S").year
• datetime(2023, 11, 3).year
• datetime.fromtimestamp(timestamp).year
• datetime.now().year
