Knowing how to check the date format is a crucial skill for anyone who works with data. Incorrectly formatted dates can lead to errors in calculations, sorting, and analysis, all of which can negatively impact the quality of decision-making. Fortunately, there are a number of simple steps that can be followed to ensure that dates are always formatted correctly.
The first step is to identify the date format that is being used. This can be done by looking at the documentation for the data source or by using a tool like the Python dateutil library. Once the date format has been identified, it can be used to check whether or not the dates in the data set are formatted correctly.
