Supported rulesets, each covered by the automated test suite:
Handles overnight shifts, per-entry rounding policies (exact / 5 min / 15 min / 0.1 h), and configurable workweek start day.
Quick 1.5× rate and overtime-pay calculation from a rate and OT hours.

Or with Claude Code:claude mcp add hourledger -- npx -y hourledger-mcp
"How much do I make this week? I worked Monday to Thursday 7am–5pm at $19/hour in Nevada."
The model callscalculate_work_hourswith the four 10-hour entries and gets back the correct Nevada answer ($19 ≥ $18 cutoff → weekly rule only → 40 regular hours, no OT), with day-by-day detail.
