The formula
Time and a half = regular rate × 1.5. That's it — $18 becomes $27, $22.50 becomes $33.75. Multiply the result by your overtime hours to get the overtime pay for the period.

When time and a half applies
Federally: hours over 40 in a workweek for non-exempt employees. Contrary to popular belief, there's no federal requirement for time and a half on weekends or holidays as such — it's the weekly hours that trigger it (holiday premiums are employer policy or union contract). Some states add daily triggers; California pays 1.5× after 8 hours in a day and 2× after 12.
