Yes, many countries around the world use daylight savings time to make better use of daylight during the longer days of the year. However, not all countries observe this practice, and some that did in the past have since stopped.
No, Guantanamo Bay in Cuba does not observe daylight saving time.
Countries such as Iceland, Belarus, and parts of Brazil have adopted daylight-saving time (DST) all year round. These countries have decided to make DST permanent to save energy, increase productivity, and make better use of daylight hours.
No Hawaii does not use Daylight Savings Time.
No. Arizona does not use daylight savings time.
To save daylight
Tonga is 13 hours ahead of GMT. As Tonga is about halfway from NZ to Hawaii, and therefore mainly tropical, they have no real use for daylight savings.
No. Arizona and Hawaii, do not use it.

Daylight Saving Time is meant to save on the cost of lighting in the evening. However, studies are starting to show that in warmer areas, the cost of the increased use of air conditioning in the late afternoon more than cancels any savings from reduced lighting, especially now that incandescent lighting is being phased out.
