ما هي حاسبة الوقت؟

A time calculator helps you find the difference between two times, add or subtract a duration from a time, convert between units (seconds, minutes, hours, days, weeks), and compute the duration between start and end times—including across midnight.

Difference = |Time 2 − Time 1|  |  Duration = End − Start (or across midnight)

Use it for work hours, travel time, project duration, or any task that requires time arithmetic or unit conversion.

تنسيق الوقت

HH:MM أو HH:MM:SS in 24-hour format. Examples: 09:00, 14:30, 23:59:59.

Hours 0–23, minutes and seconds 0–59.

أنواع الحساب

فارق التوقيت

Absolute difference between two clock times. Always a positive duration.

إضافة/طرح الوقت

Add or subtract hours, minutes, or seconds from a time. Result wraps within 24 hours.

تحويل وحدات الوقت

Convert a numeric amount from one unit to another (e.g. 2 hours to minutes, days to seconds).

حساب المدة

Duration from start to end time. If end is earlier than start, the next day is assumed (e.g. 23:00 to 02:00 = 3 hours).

كيفية استخدام هذه الآلة الحاسبة

  1. Select the mode: Time Difference, Add/Subtract, Convert Units, or Duration
  2. Enter your times or values in the shown fields (use 24-hour format for clock times)
  3. Click 'Calculate' to see the result
  4. Review the main result, detail cards (hours, minutes, seconds, total seconds), and step-by-step solution
  5. Use the chart to compare values visually
  6. Click 'Reset' to restore defaults and clear results

Main result

The primary answer: time difference or duration in HH:MM:SS, or the converted value with unit. Shown in the highlighted card at the top.

Detail cards

Hours, minutes, seconds, and total seconds break down the result. For unit conversion, the cards show input value, from-unit, result, and to-unit.

Step-by-step

Shows how the calculation was performed: converting to seconds, applying the operation, and converting back to hours, minutes, and seconds where applicable.

Understanding the Chart

The bar chart compares the relevant values in seconds: for difference or duration you see the two times and the result; for add/subtract you see start time, amount added or subtracted, and result; for conversion you see the from-value and to-value in a common unit.

ملاحظات هامة

  • Use 24-hour format (0–23). Time difference is always positive.
  • Duration can cross midnight (e.g. 23:00 to 02:00 = 3 hours).
  • All calculations use seconds internally; the chart shows values in seconds.
