A day is a unit of time, commonly defined as an interval equal to 24 hours. It also can mean that portion of the full day during which a location is illuminated by the light of the sun, also known as daytime. The period of time measured from local noon to the following local noon is called a solar day.
Several definitions of this universal human concept are used according to context, need and convenience. In 1967, the second was redefined in terms of the wavelength of light, and it became the SI base unit of time. The unit of measurement for time called "day", redefined in 1967 as 86,400 SI seconds and symbolized d, is not an SI unit, but it is accepted for use with SI. A civil day is usually also 86,400 seconds, plus or minus a possible leap second in Coordinated Universal Time UTC, and, in some locations, occasionally plus or minus an hour when changing from or to daylight saving time. The word day may also refer to a day of the week or to a calendar date, as in answer to the question "On which day?" Day also refers to the part of the day that is not night — also known as 'daytime'. The life patterns of humans and many other species are related to Earth's solar day and the cycle of day and night (see circadian rhythms).
Hello is a salutation or greeting in the English language. It is attested in writing as early as the 1830s.
Hello, with that spelling, was used in publications as early as 1833. These include an 1833 American book called The Sketches and Eccentricities of Col. David Crockett, of West Tennessee, which was reprinted that same year in The London Literary Gazette.
The word was extensively used in literature by the 1860s.[citation needed]
According to the Oxford English Dictionary, hello is an alteration of hallo, hollo, which came from Old High German "halâ, holâ, emphatic imperative of halôn, holôn to fetch, used especially in hailing a ferryman." It also connects the development of hello to the influence of an earlier form, holla, whose origin is in the French holà (roughly, 'whoa there!', from French là 'there'). As in addition to hello, halloo,hallo, hollo, hullo and (rarely) hillo also exist as variants or related words, the word can be spelt using any of all five vowels.
The use of hello as a telephone greeting has been credited to Thomas Edison; according to one source, he expressed his surprise with a misheard Hullo.Alexander Graham Bell initially used Ahoy (as used on ships) as a telephone greeting. However, in 1877, Edison wrote to T.B.A. David, the president of the Central District and Printing Telegraph Company of Pittsburgh:
Seven rainy days seven lonely nights, seven rock'n'rolls, keeps me, cheaps me, seven rainy days, seven lonely nights, seven rainy days...
I'll have to go now, my mind is plain now, I came to meet you that day, I asked if you knew where I can finally move, you said to me "I'll do, I'll show you the way".
About a mile out, I thought I'll make out had to meet you in the motel, so we checked in, didn't have a clue, got the key to two-twenty-three.
Seven rainy days, seven lonely nights, seven rock'n'rolls, keeps me, cheaps me, seven rainy days, seven lonely nights, just a week away, seven rainy days.
On the highway, no more words to say, but your right is all wrong, in the fading light it got swallowed by the night, I saw your face and her face beside me, beside me in the sky, oh ahy....
Seven rainy days, seven lonely nights, seven rock'n'rolls, keeps me, cheaps me, seven rainy days, seven lonely nights, just a week away, seven rainy days.
Do you want to ride me New York look back do you sit beside me it's a one-way turn!
