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 Create Quiz Comment C cse1604310056 Follow 0 Improve C cse1604310056 Follow 0 Improve Article Tags : Python Python-numpy Python numpy-program Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
