Fortnight. A period of 15 days or two weeks is called as Fortnight.
A fortnight is a unit of time equal to 14 days (2 weeks). The word derives from the Old English term fēowertīene niht, meaning "fourteen nights" (or "fourteen days," since the Anglo-Saxons counted by nights).
fourteen days and nights
A fortnight is “a period of two weeks,” that is, “fourteen days and nights.” The number fourteen, here, is more than just another way to gloss how long two weeks is, though. It actually explains that confusing fort- in fortnight—which has nothing to do with army forts or pillow forts.
decade f (plural decadi) a decade, a period of ten days.
What does biweekly mean? Biweekly is commonly used to mean one of two things: once every two weeks or twice per week. It can be used this way as an adjective, as in a biweekly meeting, or an adverb, as in We plan to meet biweekly.

Biweekly and bimonthly can mean the same thing because of the prefix bi-, which here can mean “occurring every two” or “occurring twice in.” Therefore, biweekly can be “twice in a week” or “every other week.” Bimonthly can also mean "every other week" if it's twice in a month, or it can mean “every other month.”
According to Merriam-Webster's Dictionary of English Usage , in the world of publishing, the former definition is almost invariably the intended one; a bimonthly magazine comes out six times a year.

Semiannual is an adjective that describes something that is paid, reported, published, or otherwise takes place twice each year, typically once every six months.
Biannual and semiannual can both mean “twice a year.” However, biannual can also mean “every two years,” and semiannual can also mean “lasting for half a year” (though this sense isn't commonly used). The best way to be clear is to just say “twice a year” or “every two years.”
Every quarter of a year (three months).
A semiannual bond compounds twice as much as an annual bond. If prevailing rates are lower than the bond's interest rate, an annual bond will have a higher price than its semiannual twin, because bond investors are willing to pay more for the extra six months of relatively high accrued interest.
Definition: Semi-Annual is the time interval or frequency of an event occurring every six months, twice a year, or semi annually.
COMPOUND INTEREST
| Compounding Period | Descriptive Adverb | Fraction of one year |
|---|---|---|
| 1 month | monthly | 1/12 |
| 3 months | quarterly | 1/4 |
| 6 months | semiannually | 1/2 |
| 1 year | annually | 1 |
Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end of two years.
8.16%
The effective rate of 8% compounded semi-annually is 8.16%.
The annual percentage yield on 6% compounded monthly would be 6.168%. Using 6.168% in the doubling time formula would return the same result of 11.58 years.
