# Date difference in days

Canonical: https://www.wiki.jodisand.me/snippets/python/days_diff/


Calculates the day difference between two dates.

- Subtract `start` from `end` and use `datetime.timedelta.days` to get the day difference.

```py
def days_diff(start, end):
  return (end - start).days
```

```py
from datetime import date

days_diff(date(2020, 10, 25), date(2020, 10, 28)) # 3
```
