```python

import context

```

```python

from edsnlp.pipelines.misc.dates import Dates, terms

```

```python

from datetime import datetime

```

```python

import spacy

```

# Date detection

```python

text = (

    "Le patient est arrivé le 23 août (23/08/2021). "

    "Il dit avoir eu mal au ventre hier. "

    "L'année dernière, on lui avait prescrit du doliprane."

)

```

```python

nlp = spacy.blank('fr')

```

```python

doc = nlp(text)

```

```python

dates = Dates(

    nlp,

    absolute=terms.absolute,

    relative=terms.relative,

    no_year=terms.no_year,

)

```

```python

dates(doc)

```

```python

doc.spans

```

```python

print(f"{'expression':<20}  label")

print(f"{'----------':<20}  -----")

for span in doc.spans['dates']:

    print(f"{span.text:<20}  {span._.date}")

```

Lorsque la date du document n'est pas connue, le label des dates relatives (hier, il y a quinze jours, etc) devient `TD±<nb-de-jours>`

Si on renseigne l'extension `note_datetime` :

```python

doc._.note_datetime = datetime(2020, 10, 10)

```

```python

dates(doc)

```

```python

print(f"{'expression':<20}  label")

print(f"{'----------':<20}  -----")

for span in doc.spans['dates']:

    print(f"{span.text:<20}  {span._.date}")

```
