// 35 days

// 10 days (legal days expired, extra days still valid)

// 0 days (legal days expired, extra days also expired)

// Take some days off:
$calculator->addUsedBalance(new UsedBalance(new \DateTime("2015-02-02"), 1));

// Before:
echo $calculator->getBalanceForDate(new \DateTime('2015-02-01')) . "\n";
// 35 days

// After:
echo $calculator->getBalanceForDate(new \DateTime('2015-02-02')) . "\n";
