How the totals are worked out
Each day is out-time minus in-time minus the break, with shifts past midnight handled automatically. The weekly total is then split at your overtime threshold — 40 hours by default, which is the US federal standard — and the overtime portion is paid at the multiplier you choose. Time-and-a-half is the common rule; some contracts pay double.
Overtime is weekly, not daily — usually
This card applies the common weekly rule: overtime starts once the week crosses the threshold, regardless of how the hours were spread. A few places (California among them) also mandate daily overtime after 8 hours; if that applies to you, the weekly figure here is a floor, not the full picture.
Why it saves locally
A time card is filled in as the week goes along, so losing it to an accidental refresh on Thursday would make the tool useless. Entries live in your browser's own storage — on your machine, never sent anywhere — and stay until you press Clear week.
Frequently asked questions
My shift runs past midnight — will it count right?
Yes. When the out-time is earlier than the in-time, the day is treated as an overnight shift; 22:00 to 06:00 counts as eight hours on the day the shift started.
Can I use it for two weeks or a month?
The grid is one week, matching how overtime is normally assessed. For longer periods, copy the weekly summary each week and add them up — or run one card per week.
Is my data stored or sent anywhere?
Nothing is uploaded. The time card is saved only in your own browser's local storage so it survives a refresh; clearing your browser data removes it.
