A timestamp is a representation of a specific point in time, expressed as a combination of date and time information. In data processing, timestamps are used to note the occurrence of events, record the time at which data was generated or modified, and provide a chronological ordering of data.
Pandas Timestamp is a data structure used to handle timestamps in time-series data analysis.
Converting Pandas Timestamps to Datetime ObjectsImporting Pandas
Python
Using the date() functionThis method extracts the date information from the Timestamp object and returns a new datetime.date object. It’s useful if you only care about the date and not the time.
Python
# Sample dataset using dictionaries
data = {
'timestamp': ['2024-01-01 12:00:00', '2024-01-02 14:30:00', '2024-01-03 08:45:00'],
'value': [10, 20, 15]
}
import pandas as pd
# Create a Timestamp object
ts = pd.Timestamp("2024-02-05 10:00:00")
# Extract the date using the date() method
date_obj = ts.date()
print(type(ts))
print(type(date_obj))
Output:
<class 'pandas._libs.tslibs.timestamps.Timestamp'> <class 'datetime.date'> Using the to_pydatetime() functionFirst, we create a timestamp object using Components (year, month, day, hour, minute, second, microsecond) and convert it to a DateTime object using the Pandas.to_pydatetime() function.
Python
# Create a Pandas Timestamp object
ts =pd.Timestamp(year=2024, month=1, day=28, hour=15, minute=30, second=0, microsecond=0)
# Convert the Timestamp to a Python datetime object
datetime_obj = ts.to_pydatetime()
print(datetime_obj)
print(type(datetime_obj))
Output:
2024-01-28 15:30:00-05:00 <class 'datetime.datetime'> Pandas Timestamp To Datetime – FAQsHow to Convert String Timestamp to Datetime in Python?To convert a string representation of a timestamp into a datetime object, you can use the datetime.strptime() method from the datetime module, which allows you to specify the format of the timestamp:
from datetime import datetime
# Example string timestamp timestamp_str = '2021-09-01 12:45:00'
# Convert string to datetime datetime_obj = datetime.strptime(timestamp_str, '%Y-%m-%d %H:%M:%S') print(datetime_obj)
How to Convert Timestamp into String?To convert a datetime object back into a string with a specified format, use the strftime() method:
# Convert datetime object to string timestamp_str = datetime_obj.strftime('%Y-%m-%d %H:%M:%S') print(timestamp_str)
How to Calculate Date from Timestamp?If you have a Unix timestamp (number of seconds since January 1, 1970), you can convert it into a readable date using datetime.fromtimestamp() :
# Example Unix timestamp unix_timestamp = 1630496700
# Convert timestamp to datetime date_time = datetime.fromtimestamp(unix_timestamp) print(date_time)
How to Convert Date to Datetime in Python?If you start with a date object or a date string and want to convert it to a datetime object, here’s how you can do it:
from datetime import date
# If you have a date object date_obj = date(2021, 9, 1)
# Convert date to datetime at the beginning of the day datetime_obj = datetime.combine(date_obj, datetime.min.time()) print(datetime_obj) If you’re converting from a date string, use strptime() as shown in the first example but with the appropriate format.
What is the Difference Between Datetime and Timestamp in Python?- Datetime: In Python,
datetime refers to the datetime object in the datetime module, which represents both a date and a time in one object. It’s used for more complex date and time manipulations in Python. - Timestamp: A timestamp generally refers to a specific point in time often represented as a string or a number. In Unix systems, it is commonly the number of seconds that have elapsed since January 1, 1970 (also known as Unix time).
