functions Shows the working, not just the answer
For students and teachers, the final number is only half the value. Every math tool here exposes the formula it applied, the intermediate steps, and the rounding rule, so you can follow along, check your homework, or use the answer in a proof or report with confidence.
calculate Accurate to the spec
Calculations use 64-bit floating point with sensible rounding for the domain (currency to 2 decimals, percentages to 4 decimals, algebra to 6 significant figures). Where exact rational arithmetic matters — fractions, factorials, simplification — we use a dedicated BigNumber path so 1/3 + 1/6 returns ½, not 0.49999.

Formula & methodology
Formula: Reset complete = start date and time + 34 hours
- Enter the date and time your restart period begins.
- The tool adds exactly 34 hours to that moment.
- It returns the date and time your hours-of-service clock resets.
- Once the clock reaches that time, your 60/70-hour limit is refreshed.
Example: a restart beginning 6:00 PM on 9 June 2026 completes at 4:00 AM on 11 June 2026, refreshing your weekly hours.
