## Implementation

```javascript
function isBetween({ date, min, max }) { const time = Date.parse(date); return time >= Date.parse(min) && time <= Date.parse(max); }
```

## Input

```json
{
  "date": "2026-10-28",
  "min": "2026-10-01",
  "max": "2026-10-31"
}
```

## Expected output

```json
true
```

## Edge case

Input:
```json
{
  "date": "2026-11-01",
  "min": "2026-10-01",
  "max": "2026-10-31"
}
```
Output:
```json
false
```

## Limits

- Both ends are included. Dates are UTC calendar days, so the machine’s time zone does not matter.

The lab validates types and size before calling this function. Add equivalent validation at your own trust boundary.
