Get First Day of Next Month in Python

Get First Day of Next Month in Python

This tutorial will demonstrate how to get first day of next month in Python.

Using the datetime.replace() with datetime.timedelta() function

To get first day of next month in Python:

  • Use the datetime object to store the current date and time.
  • Use the datetime.replace() and datetime.timedelta() function to get first day of next month in Python.

See the code below.

Output:

2023-01-01 02:59:52.077793

The datetime library is used to work with date and time values in Python. The datetime object can store such values and provide different methods to operate on them. The now() function returns the current date and time values.

The replace() function from this library can be used to replace values of different attributes from such objects. The timedelta object from this library can be used to represent different intervals of time.

In the code example above, we use these methods to get the first day of next month by adding one month to the datetime value and replacing the value of the day attribute with one.

Using the calendar.monthrange() function

To get first day of next month in Python:

  • Use the datetime object to store the current date and time.
  • Use the monthrange() function to get the days of month.
  • Use the replace() and timedelta() functions to get first day of next month in Python.

See the code below.

Output:

2023-01-01 03:52:36.547092

The calendar library also provides an additional set of tools to work with datetime objects.

The monthrange() function is used to calculate the first day of month and the days of the month. In the above example, we use the days of the month value and add it to the current date. Then we replace the value of the day attribute with one.

Using the dateutil.relativedelta object

To get first day of next month in Python:

  • Use the datetime object to store the current date and time.
  • Use the datetime.relativedelta object to get first day of next month in Python.

See the code below.

Output:

2023-01-01 03:21:55.474191

The dateutil library provides an additional set of methods and objects to work with datetime objects. The relativedelta object is used to replace and add different intervals of time to datetime objects.

In the above example, we use the relativedelta object to get first day of next month in Python.

Conclusion

To conclude, we discussed several methods to get first day of next month in Python.

In the first method, we use the replace() function to replace the value of the day attribute and add a time interval using the timedelta object. In the next method, we follow the same logic as method one but we use the monthrange() function to obtain the value that needs to be added with the timedelta object.

In the final method, we discussed the dateutil library and the relativedelta object from this library to add and replace time values to get the first day of month in Python.
