(Usually I'm working the other way to get an hourly number from an annual salary but the math works both ways.)
Yeah that's more correct than twelve twenty-day months. In my locale, wages are expressed monthly so I'm a bit more used to roughly divide by twenty, for instance when calculating the relative cost of daycare.
who in software gets paid an hourly wage?
People I know at Apple are hourly.
Is there a good reason to pay on a hourly basis?
overtime is normally $hourly * 1.5 or so depending on the company
