実労働時間・休憩控除・概算給与を正確に計算

Tracking employee attendance, freelance project billing, and daily shift records is fast and error-free with our free timesheet calculator and online timeline calculator. Designed for employees, independent contractors, remote freelancers, and team managers, this tool eliminates the headache of calculating daily work time cards and weekly timesheet summaries manually.

Simply enter your shift start and end times to immediately view your net hours worked. The timeline calculator automatically deducts unpaid lunch breaks and rest periods. It includes dedicated logic for overnight shifts, seamlessly managing work periods that cross the midnight threshold without negative hour calculations. In addition, the engine converts elapsed time into decimal hours (for instance, converting 8 hours and 15 minutes into 8.25 decimal hours), making it effortless to copy directly into corporate payroll, QuickBooks, or client invoices.

Unlike cloud-based attendance software that requires subscription accounts or stores your personal schedule on external databases, this free timesheet calculator operates 100% locally in your web browser. Your salary rates, shift timings, and earnings data remain strictly confidential on your own device.
