Although employees may accrue more than three days of paid sick leave under the one hour for every 30 hours worked (or under an alternative accrual standard) under an accrual method, the law allows employers to limit an employeeâs use of paid sick leave to 24 hours or three days during a year.
Modern piano keyboards ordinarily have an octave span of 164â165 mm; resulting in the width of black keys averaging 13.7 mm and white keys about 23.5 mm wide at the base, disregarding space between keys. Several reduced-size standards have been proposed and marketed.
You then have understood the an octave is a group of 8 white keys and 5 black keys giving the total of 13 keys per octave. You also understand that the 88 keys on the piano isnât just about the octaves, as the total keys in the octave are 85 and that there are 3 more keys to find.
