How to Add or Subtract Days to a Date

• Convert the date to a datetime object. You can use the datetime.datetime() function to do this.
• Add or subtract the desired number of days to the datetime object. You can use the datetime.timedelta() function to do this.
• Convert the datetime object back to a date. You can use the datetime.date() function to do this.

                import datetime

                # Convert the date to a datetime object.
                date = datetime.datetime(2023, 9, 27)

                # Add 10 days to the date.
                new_date = date + datetime.timedelta(days=10)

                # Subtract 5 days from the date.
                new_date = date - datetime.timedelta(days=5)

                # Print the new date.
                print(new_date)

• Create a new Date object. You can do this using the new Date() constructor.
• Set the date of the Date object. You can use the setDate() method to do this.
• Add or subtract the desired number of days to the Date object. You can use the setDate() method to do this, passing in the new day of the month.
• Return the Date object.

                // Create a new Date object.
                const date = new Date();

                // Add 10 days to the date.
                date.setDate(date.getDate() + 10);

                // Subtract 5 days from the date.
                date.setDate(date.getDate() - 5);

                // Return the Date object.
                console.log(date);

                // Add 10 days to the date.
                date.addDays(10);

                // Subtract 5 days from the date.
                date.subtractDays(5);
