  Month (730h)

  A month is a unit of time, used with calendars, which is approximately as long as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of Moon phases; such months (lunations) are synodic months and last approximately 29.53 days. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moon's phases as early as the Paleolithic age. Synodic months, based on the Moon's orbital period with respect to the Earth-Sun line, are still the basis of many calendars today, and are used to divide the year.

  Second (0.00027777h)

  The second is the SI base unit of time, commonly understood and historically defined as 1⁄86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Another intuitive understanding is that it is about the time between beats of a human heart. Mechanical and electric clocks and watches usually have a face with 60 tickmarks representing seconds and minutes, traversed by a second hand and minute hand. Digital clocks and watches often have a two-digit counter that cycles through seconds. In common parlance, a "clock tick" is a second, though most modern clocks are digital electronic, and do not actually tick. The second is also part of several other units of measurement like velocity, acceleration, and frequency. Though the historical definition of the unit was based upon this division of the Earth's rotation cycle, the formal definition in the International System of Units SI is a much steadier timekeeper: 1 second is defined to be exactly 9 192 631 770 cycles of a Caesium atomic clock. Because the Earth's rotation varies and is also slowing ever so slightly, a leap second is added to clock time to keep clocks in sync with Earth's rotation.
