How to Add One Day to a Date

How to add one day to a date?

Given a Date dt you have several possibilities:

Solution 1: You can use the Calendar class for that:

Date dt = new Date();
Calendar c = Calendar.getInstance(); 
c.setTime(dt); 
c.add(Calendar.DATE, 1);
dt = c.getTime();

Solution 2: You should seriously consider using the Joda-Time library, because of the various shortcomings of the Date class. With Joda-Time you can do the following:

Date dt = new Date();
DateTime dtOrg = new DateTime(dt);
DateTime dtPlusOne = dtOrg.plusDays(1);

Solution 3: With Java 8 you can also use the new JSR 310 API (which is inspired by Joda-Time):

Date dt = new Date();
LocalDateTime.from(dt.toInstant()).plusDays(1);

Adding one day to a date

<?php
$stop_date = '2009-09-30 20:24:00';
echo 'date before day adding: ' . $stop_date; 
$stop_date = date('Y-m-d H:i:s', strtotime($stop_date . ' +1 day'));
echo 'date after adding 1 day: ' . $stop_date;
?>

For PHP 5.2.0+, you may also do as follows:

$stop_date = new DateTime('2009-09-30 20:24:00');
echo 'date before day adding: ' . $stop_date->format('Y-m-d H:i:s'); 
$stop_date->modify('+1 day');
echo 'date after adding 1 day: ' . $stop_date->format('Y-m-d H:i:s');

Add one day to date in javascript

Note that Date.getDate only returns the day of the month. You can add a day by calling Date.setDate and appending 1.

// Create new Date instance
var date = new Date()

// Add a day
date.setDate(date.getDate() + 1)

JavaScript will automatically update the month and year for you.

Here's a link to a page where you can find all the cool stuff about the built-in Date object, and see what's possible: Date.

Adding days to a date in Python

The previous answers are correct but it's generally a better practice to do:

import datetime

Then you'll have, using datetime.timedelta:

date_1 = datetime.datetime.strptime(start_date, "%m/%d/%y")

end_date = date_1 + datetime.timedelta(days=10)

How to add a 1 day to today's date in python?

You are trying to do date operations on strings and not using the result of your formatting call:

s = date.today()
modified_date = s + timedelta(days=1)
modified_date = modified_date.strftime("%Y-%m-%d")  # this would be more common
# modified_date = datetime.strftime(modified_date, "%Y-%m-%d")

print(modified_date)
