# tf_quant_finance.datetime.daycount_actual_365_actual
View source
Computes the year fraction between the specified dates.
```python
tf_quant_finance.datetime.daycount_actual_365_actual(
*, start_date, end_date, schedule_info=None, dtype=None, name=None
)
```
The actual/365 actual convention specifies the year fraction between the
start and end date as the actual number of days between the two dates divided
365 if no leap day is contained in the date range and 366 otherwise.
When determining whether a leap day is contained in the date range,
`start_date` is excluded and `end_date` is included.
Note that the schedule info is not needed for this convention and is ignored
if supplied.
#### Args:
* `start_date`: A `DateTensor` object of any shape.
* `end_date`: A `DateTensor` object of compatible shape with `start_date`.
* `schedule_info`: The schedule info. Ignored for this convention.
* `dtype`: The dtype of the result. Either `tf.float32` or `tf.float64`. If not
supplied, `tf.float32` is returned.
* `name`: Python `str` name prefixed to ops created by this function. If not
supplied, `actual_365_actual` is used.
#### Returns:
A real `Tensor` of supplied `dtype` and shape of `start_date`. The year
fraction between the start and end date as computed by Actual/365 Actual
convention.
