Python | Pandas Timestamp.fromordinal
Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Pandas Timestamp.fromordinal() function return a Timestamp object when passed an ordinal, the function translate and convert it to a ts object. By definition there cannot be any tz info on the ordinal itself.
Syntax :Timestamp.fromordinal()
Parameters :
ordinal : date corresponding to a proleptic Gregorian ordinal
freq : Offset which Timestamp will have
tz : Time zone for time which Timestamp will have
Return : Timestamp
Example #1: Use Timestamp.fromordinal() function to translate the given Timestamp object based on the passed ordinal value.
# importing pandas as pd import pandas as pd   # Create the Timestamp object ts = pd.Timestamp(year = 2011, month = 11, day = 21,                   hour = 10, second = 49, tz = 'US/Central')   # Print the Timestamp object print(ts) |
Output :
Now we will use the Timestamp.fromordinal() function to convert the given Timestamp object.
# convert the given Timestamp object # based on the passed ordinal value ts.fromordinal(ordinal = 733829) |
Output :
As we can see in the output, the Timestamp.fromordinal() function has returned a new Timestamp object based on the passed ordinal value.
Example #2: Use Timestamp.fromordinal() function to translate the given Timestamp object based on the passed ordinal value. Also set the timezone.
# importing pandas as pd import pandas as pd   # Create the Timestamp object ts = pd.Timestamp(year = 2009, month = 5, day = 31,                   hour = 4, second = 49, tz = 'Europe/Berlin')   # Print the Timestamp object print(ts) |
Output :
Now we will use the Timestamp.fromordinal() function to convert the given Timestamp object.
# convert the given Timestamp object # based on the passed ordinal value ts.fromordinal(ordinal = 634816, tz = 'Asia / Calcutta') |
Output :
As we can see in the output, the Timestamp.fromordinal() function has returned a new Timestamp object based on the passed ordinal value. The function has also set the timezone for the returned Timestamp object.
