What is the time difference between California and Hawaii?

Answer:
The time difference between California and Hawaii can vary depending on the time of the year due to Daylight Saving Time (DST) practices. Here is the detailed explanation:

  1. Standard Time (Non-DST Periods):

    • California is in the Pacific Time Zone (PT), which is UTC-8.
    • Hawaii is in the Hawaii-Aleutian Standard Time Zone (HAST), which is UTC-10.
    • During this time, the time difference between California and Hawaii is 2 hours. This means when it is 12:00 PM (noon) in California, it is 10:00 AM in Hawaii.
  2. Daylight Saving Time (DST) Periods:

    • California observes Daylight Saving Time, shifting to Pacific Daylight Time (PDT), which is UTC-7.
    • Hawaii does not observe Daylight Saving Time and remains at UTC-10.
    • During DST, the time difference increases to 3 hours. Thus, when it is 12:00 PM (noon) in California during DST, it is 9:00 AM in Hawaii.

Summary of Time Differences:

  • Standard Time (November to March/early April): 2-hour difference.
  • Daylight Saving Time (March/early April to November): 3-hour difference.

Example Calculation:

  • If it’s February (non-DST period) and 3:00 PM in California:
    $$ \text{Hawaii time} = \text{California time} - 2 \text{ hours} $$
    $$ = 3:00 \text{ PM} - 2 \text{ hours} = 1:00 \text{ PM} \text{ in Hawaii} $$

  • If it’s June (DST period) and 3:00 PM in California:
    $$ \text{Hawaii time} = \text{California time} - 3 \text{ hours} $$
    $$ = 3:00 \text{ PM} - 3 \text{ hours} = 12:00 \text{ PM} \text{ (noon) in Hawaii} $$

Therefore, the time difference between California and Hawaii is generally 2 hours during Standard Time and 3 hours during Daylight Saving Time.
