Calling DST "summer time" may confuse people since that phrase is not used here in that manner.

The only states that do not observe DST are A.rizona* and H.awaii.

*The Navajo nation, which is mostly in Arizona, does observe because they have territory in neighboring states and they want the entire area to be consistent.

It is called Daylight Savings Time, and the entire country moves its clocks forward 1 hour in Spring, usually around mid April, and then in Fall, they move them back 1 hour, usually end of Oct.

Spring Forward, Fall Back. Besides the states listed above, parts if Indiana near Terre Huate also are on a different schedule..or at least they used to be.

#3, the schedules were changed in 2005, effective 2007. It's now the Sundays of the second week of March and first week of November.
Also, Indiana started completely observing when it moved some counties from eastern time to central time.

Sorry, left part out. Indiana moved the counties in 2006.

Some Arizona Indian reservations also do not observe it, although other reservations next door do. This was in Tuba City, Arizona.

#6, in AZ, only the Navajo use it. See #2.

I want to know why the poster needs to know this, as there are still 4 times zones regardless, so what difference does it make. You Pacific, Mountain, Central, and Eastern.

SoloHobo - It's not time zones - I think the OP is confusing seasons of the year with the terminology used to describe adjusting the clock to daylight savings time since some countries refer to daylight savings time as summertime.

OP - In the U.S. summer means the season of the year from June through August. Changing the time one hour forward or backward is called "daylight savings time" and clocks are adjusted back one hour in the fall (daylight savings time) and forward one hour in the spring (standard time).

This is what is confusing your receptionist (althought the one you talked to sounds like she may be permanently confused).

From Wikipedia...
http://en.wikipedia.org/wiki/Daylight_saving_time

Although daylight saving time is considered to be correct, daylight savings time (with an "s") is commonly used. The form daylight saving time uses the present participle saving as an adjective, as in labour saving device; the first two words are sometimes hyphenated, as in daylight-saving time. The common variants daylight savings time and daylight savings use savings by analogy to savings account. Daylight time is also common. Willett's 1907 proposal used the term daylight saving, but by 1911 the term summer time replaced daylight saving time in draft legislation in Britain, and continental Europe uses similar phrases, such as Sommerzeit in Germany, zomertijd in Dutch, horario de verano or hora de verano in Spain and l'heure d'été in France, whereas in Italy the term is ora legale, that is, legal time (legally enforced time) as opposed to "ora solare", solar time, in Winter.

The name of local time typically changes when DST is observed. American English replaces standard with daylight: for example, Pacific Standard Time (PST) becomes Pacific Daylight Time (PDT). British English calls UK time British Summer Time (BST), and typically inserts summer into other time zones, e.g. Central European Time (CET) becomes Central European Summer Time (CEST). Abbreviations do not always change: for example, many (though not all) Australians say that Eastern Standard Time (EST) becomes Eastern Summer Time (also EST). In Australia it is also called EDT (Eastern Daylight Time)
