About Mallow Hours
A small time card calculator for people who want to check their work hours and reuse a schedule next week.
What this tool does
Mallow Hours adds weekly or biweekly shifts, subtracts unpaid breaks, checks overlaps and exports a readable record. You can save a card on this device, duplicate it, or carry the schedule into the next period. No account is required.
What the numbers mean
Times are clock-face minutes. Overnight shifts belong to their start date; a manual adjustment can account for a daylight saving change that you have independently checked. Weekly overtime uses your chosen threshold for each seven-day block. Estimated pay rounds once, half up, to two decimals.
What it does not do
This is not an attendance system, payroll service, employment-law calculator or tax adviser. It does not know paid-break policies, daily overtime, holiday premiums, time zones or statutory rounding rules. Check employer requirements before relying on an exported card.
Part of MallowDesk
MallowDesk is an independent collection of small browser tools. Hours owns its own local records and does not automatically share them with Timer, Invoice or other apps. Feedback about a reproducible calculation or accessibility issue helps us improve the tool.
