Re: Django get queryset year month day

[Leonardo Giordani]

If I correctly understand you issue is to get part of the date for each
item in a list of datetime.datetime or datetime.date objects.
To do this you can process the list after the query

new_list = [item.year for item in item]

But if your need is to extract fields from the objects in the result list
you may use 
values()or
values_list()
.

Let me know if this answers your question.

Regards,

Leo
