Time Converter

There are 86,400 seconds in a day (24 hours × 60 minutes × 60 seconds). This value is widely used in programming, physics and astronomy. Note that leap seconds occasionally adjust atomic time to match Earth's rotation, but these are not relevant for everyday conversions.

To convert hours to days, divide by 24. For example, 72 hours equals 3 days. This conversion is common in project management, travel planning and medical contexts where medication schedules or recovery times are expressed in hours.

The average month has approximately 30.4375 days, calculated as 365.25 days per year divided by 12 months. This accounts for the varying lengths of calendar months and the extra day in leap years. For precise date arithmetic it is better to use calendar date functions than to multiply by this average.

There are approximately 31,557,600 seconds in a year (365.25 days × 86,400 seconds per day). This is a common approximation used in science and engineering. A simpler rule of thumb is 'about 31.5 million seconds in a year' or roughly π × 10⁷ seconds.

To convert minutes to hours, divide by 60. For example, 150 minutes equals 2.5 hours. This is one of the most common time conversions and is used in fitness tracking, billing, travel time estimates and work hour calculations.
