We need to find the day of the week by date, but the formula does not work:

```
(d + float (2.6 * m -0.2) -2 * c+ y + float (y /4) + float (c /4))
```

turns out to be a negative number ...

Is it necessary through this formula? Such a condition? In the plan, there are many other options, how can you find the day of the week by date, maybe they will suit you?
