How do you decide on which side you perform your data manipulation when you can either do it in the code or in the query ?

When you need to display a date in a specific format for example. Do you retrieve the desired format directly in the sql query or you retrieve the date then format it through the code ?

What helps you to decide : performance, best practice, preference in SQL vs the code language, complexity of the task... ?
