Degree-Day Calculator
=====================

[](#degree-day-calculator)

The calculator offers two methods for calculating degree-days using daily temperatures and upper/lower cutoff(s):

- `degreedays()` (alias `dd()`): calculates using the single-sine method [more info](http://ipm.ucanr.edu/WEATHER/ddconcepts.html)
- `degreedaysAvg()`: less accurate, it uses an approximate formula using just the mean temperature

```
use WsuDas\Degreedays\Calculator;

$dd = Calculator::degreedays($tmax, $tmin, $lower, $upper, $cutoff);
```
