I have a model which contains date range i want to filter the data based on the range date
that is i want the data who's date range is 90 days from today's date.

```
class MyModel(models.Model):
    name = models.CharField(max_length=255)
    start_end_date = ranges.DateTimeRangeField(validators= 
                                                       [validate_range_date_time])

```

so when we select the start date on page the end date will popoulate the same date but i cannot concatenate filter just by today date + timedelta(days=90) this is one single date and the field is date range, so how can i filter the date range data which is 90 days from now.

the model stores start\_end\_date as

```
'start_end_date': DateTimeTZRange(datetime.datetime(2022, 11, 29, 9, 15), datetime.datetime(2022, 11, 29, 10, 0),

 Mymodel.objects.filter(start_end_date__contains=timezone.now() + timezone.timedelta(days=90))

timezone.now() + timezone.timedelta(days=90) = datetime.datetime(2022, 11, 29, 22, 52, 7, 759648)

```

the query is giving empty set
