Get the dates of Yesterday, Today, and Tomorrow using NumPy Last Updated : 26 Nov, 2020 Comments Improve Suggest changes Like Article Like Report In NumPy with the help of NumPy.datetime64('today', 'D'), we will find today date and if we want some date before today then we will subtract the no-of-date with the help of np.timedelta64() from today. And if we want some date after today then we will add the no of date with the help of np.timedelta64() from today. For yesterday, we will subtract 1 date, for tomorrow we will add 1 date. Example #1: Get the dates yesterday, today, and tomorrow. Python3 import numpy as np # for today today = np.datetime64('today', 'D') print("Today: ", today) # for yesterday yesterday = np.datetime64('today', 'D') - np.timedelta64(1, 'D') print("Yestraday: ", yesterday) # for tomorrow tomorrow = np.datetime64('today', 'D') + np.timedelta64(1, 'D') print("Tomorrow: ", tomorrow) Output: Today: 2020-08-15 Yestraday: 2020-08-14 Tomorrow: 2020-08-16 Example #2: Get the dates in the interval. Python3 import numpy as np # for today today = np.datetime64('today', 'D') print("Today: ", today) # for before_2_day before_2_day = np.datetime64('today', 'D') - np.timedelta64(2, 'D') print("before_2_day : ", before_2_day) # for after_2_day after_2_day = np.datetime64('today', 'D') + np.timedelta64(2, 'D') print("after_2_day :", after_2_day) Output: Today: 2020-08-15 before_2_day : 2020-08-13 after_2_day : 2020-08-17 Comment More infoAdvertise with us Next Article Get the dates of Yesterday, Today, and Tomorrow using NumPy C cse1604310056 Follow Improve Article Tags : Python Python-numpy Python numpy-program Practice Tags : python Similar Reads Get Yesterday's date using Python Prerequisite: datetime moduleIn Python, date and time are not a data type of its own, but a module named datetime can be imported to work with the date as well as time.

It works exactly like relativedelta in terms of the keyword args we pass in. DateOffsets work as follows, each offset specify a set of dates that conform to the DateOffset. For example, Bday defines this set to be the 3 min read Python | Pandas Timestamp.weekday Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages.
