# Time Card Calculator > Free Time Card Calculator for US workers. Calculate work hours, breaks, and overtime instantly. No sign-up. No cost. Ever. ## Home Time Card Calculator is a free online tool designed by payroll experts for employees, freelancers, and small business owners. Enter your clock-in time, clock-out time, and break duration to instantly calculate total hours worked, including overtime. Supports both 12-hour AM/PM and 24-hour military time formats. Follows official US Department of Labor FLSA overtime guidelines. Supports both federal overtime (40 hours/week) and California overtime rules (8 hours/day). Works on desktop and mobile. Export timesheets as PDF, Excel, or CSV. ## California Overtime California overtime rules go beyond federal FLSA standards. Daily overtime kicks in after 8 hours worked in a single day at 1.5x pay, and after 12 hours at 2x pay. Weekly overtime applies after 40 hours. The calculator supports both federal and California overtime modes - select your state in settings and the correct rules apply automatically. ## Military Time Military time uses a 24-hour clock running from 0 (midnight) to 23 (11 PM). Instead of resetting at noon like the 12-hour AM/PM system, every hour of the day has a unique number. The time card calculator supports military time input for workplaces that use 24-hour clock formats. ## Timesheet Templates TimeSheet Pro is a free downloadable Excel timesheet template. Enter time-in, time-out, and break time and the sheet automatically calculates worked hours, regular pay, overtime pay, and gross pay. Includes a monthly summary tab. No macros, no signup, no cost. Supports custom overtime thresholds and multipliers. Print-ready PDF export. Includes dedicated weekly, biweekly, and monthly timesheet template variants. ## Guides Free guides covering time card and payroll topics for US workers, cross-referenced with official US labor law sources including the FLSA, the California Labor Commissioner's Office, and IRS guidelines for self-employed workers. ### Colorado Labor Laws Complete guide to Colorado labor laws for 2026, covering minimum wage, the COMPS Order, daily overtime (after 12 hours/day or 12 consecutive hours, in addition to the 40 hour/week federal standard), meal and rest breaks, paid sick leave under the Healthy Families and Workplaces Act (HFWA), Colorado's own paid family leave program (FAMLI), at-will employment, final paycheck rules, and child labor laws.
