The phrase for something that occurs four times per month but does not happen every week is "four times a month." This can happen if the events fall on specific days, such as the first, second, third, and fourth of each month, which may not align with weekly occurrences. Another example could be an event that happens on certain weekdays, resulting in some weeks having no occurrence.
An event that occurs every 18 months is often referred to as a "biennial" event, although "biennial" typically means every two years. In a more specific context, it may be described as an "18-month cycle" or "semiannual" depending on the nature of the event. In scientific or astronomical contexts, specific terms might be used to denote cycles of that length, but there isn't a widely recognized single term for an 18-month event.
"Monthly" can function as both an adjective and an adverb. As an adjective, it describes something that occurs once a month, such as a "monthly meeting." As an adverb, it indicates the frequency of an action, as in "We meet monthly."
Bimonthly.
"n"
The letter "n"
Implies that something occurs once every month.
Something that occurs TWICE a month is called SEMI monthly (semi=half) and something that occurs every TWO months is called BI-Monthly (BI=TWO)
It means twice a month. For example, we pay our water and electricity bills bi-monthly.
Biweekly occurs every other week (e.g., every two weeks). Bimonthly occurs two times a month. Essentially it is the same thing, but there is a fine difference.
No, they occur every twice a month; every full moon and every new moon.
A blue moon occurs when two full moons happen in one month. Since one full moon occurs every 28 days, it doesn't happen very often, hence the phrase.
Your question is wrong. It should be: What occurs 4 times in every week, 2 times in every month, 1 time in a year but never in a day? The question should be interpreted as What occurs 4 times in "every week", 2 times in "every month", 1 time in "a year" but never in "a day"? The answer is the letter "e", which occurs 4 times in "every week", 2 times in "every month", 1 time in "a year", but does not occur in "a day".
why does a lunar or solar eclipse not occurs every month?
Yes the moon comes out as full moon once every month
If something happens twice a month it is called biweekly because it happens every other week and a month has 4 weeks. there is also bimonthly which is every other month but not really a direct word for something that happens twice a month.
A bimonthly is a publication which occurs either once every two months or twice a month.
The expression "once in a blue moon" originates from the occurrence of a rare event. A blue moon refers to the second full moon in a calendar month, which happens infrequently, approximately every two to three years. Thus, the phrase signifies something that happens very rarely.
