Advertencia de tiempo de ejecución: El campo DateTimeField Model.date recibió una fecha y hora ingenuas mientras el soporte de zona horaria está activo.

Estoy intentando filtrar un conjunto de consultas para obtener todas las publicaciones de este año.

Django se queja de que la declaración de start_day y end_day puede estar en conflicto con django.utils.timezone, pero creo que no es un gran problema.

Pero la advertencia es molesta, cualquier sugerencia para deshacerse de ella (sin deshabilitar la advertencia de Django) será apreciada, algo como cómo obtener el primer día del año y el último de django.utils.

Aquí está el módulo implementado en mi proyecto que tiene métodos que pueden ayudarte.
