***** The Professional Time & Date Calculator Built for Real Work ***** You are the kind of person who likes to get the numbers right the first time, and that is exactly where this app earns its place. Time & Date Calculator Pro gives you quick, practical tools for work hours, date math, shifts, overtime, business days, countdown planning, and more, without making you fight through a bloated spreadsheet or a crowded all-in-one screen. Whether you are checking a timesheet before payroll, planning a deadline, comparing two dates, converting time units, or reviewing a long shift, the app keeps each calculator focused on the job in front of you. Why people keep coming back to it: - Fast answers for real-world time math. - Clear screens instead of one overloaded calculator. - Large inputs that are easy to use on iPhone and iPad. - Results written in plain language, not cryptic formulas. - Practical tools that help before work, during work, and after work. What you can do inside the app: - Add and subtract hours, minutes, and seconds. - Compare times in 12-hour AM/PM format. - Compare times in 24-hour format. - Convert time values between common units. - Total time in multi-column layouts. - Multiply and divide time for billing, batching, classes, routes, workouts, and estimates. - Find the difference between two dates. - Add an interval to a date and time. - Count business days and working hours. - Build countdown plans around deadlines and work windows. - Review shift rounding, unpaid breaks, and overtime totals. - Export weekly shift summaries. - Check flight block, duty, rest, UTC, and night-time snapshots. - Use Julian and calendar reference tools when needed. Especially useful for: - Employees checking work hours before they submit them. - Managers reviewing schedules and staffing hours. - Payroll and admin teams confirming totals. - Freelancers and contractors billing by time. - Dispatch, operations, healthcare, construction, education, and field work. - Pilots and aviation users who need quick duty and block checks. - Anyone planning around deadlines, events, appointments, and recurring schedules. Why it works better than doing it by hand: - Hours and minutes do not behave like decimals. - Overtime and rounding rules are easy to misread. - Business-day planning gets messy when weekends and work windows matter. Helpful for everyday work: - Check a full shift from start time to end time. - Subtract breaks and see paid time clearly. - Review raw hours, rounded hours, and overtime. - Compare planned hours with actual hours. - Count how many business days remain before a due date. - Work backward from a deadline with countdown planning. - Turn time values into clean numbers for notes, payroll, or scheduling. Helpful outside work too: - Count down to appointments, classes, trips, and important dates. - Compare dates without opening a spreadsheet. - Split time blocks for studying, training, routines, and projects. - Add days, hours, and minutes to see when something will land. - Keep date and duration checks quick and readable. What makes it feel practical: - Separate calculators for separate jobs. - Quick reset, save, share, copy, and guide actions where they help. - Saved state on many screens so repeated workflows are faster. - A focused layout that stays readable even when the math is not simple. - Tools built around the way people actually check hours and dates. If your day depends on shifts, payroll hours, deadlines, staffing plans, business days, countdowns, or exact time totals, this is the kind of app that saves frustration before it starts. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Time & Date Calculator Pro is built for people who care enough to double-check the details. When the hours matter, the dates matter, and the schedule matters, it helps you get the answer and move on.
Version History ***** A Faster, Cleaner Time & Date Workspace ***** This update brings a major refresh to the way the app handles everyday time math, date tracking, work-hour calculations, and Pro workflows.
