Measuring Time

Time is the measurement of the sequence and duration of events occurring in the past, present, and future. Time is a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.^[1]

Calendars, clocks and watches are all instruments for measuring time. Calendars can be used to measure years, months, and days, while clocks can be used to measure hours, minutes, and seconds.

A year is equal to 12 months, a month is equal to 28-31 days, a day is equal to 24 hours, an hour is equal to 60 minutes, and a minute is equal to 60 seconds.

The table below compares common measures of time. Use the unit conversion tools above to convert from one unit of time to another unit of time.

Units of Time Measurement

Units of time include centuries, decades, years, months, weeks, days, hours, minutes, seconds, milliseconds, microseconds, and nanoseconds.
