Info about "Decade"

A decade represents a period of ten years. Like the year itself, the decade is not part of the international system of units.

Decades (Ancient Greek: dekás, from ten) are often used in historiography or in politics to define certain goals for a particular decade. Colloquially, decades are often used to represent a period of time, by speaking of the eighties or nineties. For example, to refer to the decades from 1980 to 1989 or from 1990 to 1999.

In medicine, decades are also used to describe the increased incidence of a disease at a certain age. The disease can occur in the 3rd to 5th decade, which means that the disease occurs at the age of approximately 20 to 50 years. Similar to counting centuries (1900 to 1999 is equivalent to 20th century), one must pay attention here. For example, the third decade begins with 20 years.

Info about "Month"

A month forms the time span of 28, 29, 30 or 31 consecutive days. Due to its varying length, the month is not a physical unit of time and thus not a unit of time in the international SI system of units.

To enable a general conversion (e.g., into seconds, minutes or years), the average length of the month in days is defined: Since a year comprises 12 months, a normal calendar year with 365 days results in a month length of 365 / 12 = 30.416667 days

In astronomical terms, a month is defined as the period of one complete revolution of the moon. Depending on the definition, the lunar month is a little more than 28 days on average.
