Does my age depend on the current timezone?

If I turn, say, 18 at home, and immediately travel westwards into a different time zone where it's still the previous day, will I be legally 17 or 18 there?

And if 17, how would that affect e.g. any rules that would require me to be of age for that specific journey (can't think of any specifics, and yes this is getting rather academical now).

This question is about the legal aspects, not the practical side of how to actually do it.

Do time zones affect your age?

Your age is judged according to to the local time. So if you're born in Australia and travel to the US a day before your 21st birthday then it doesn't matter that the clock has hit midnight making you 21 in Sydney, you can't (legally) start getting drunk in San Francisco.

What determines your time zone?

As Earth rotates on its axis, it moves about 15 degrees every 60 minutes. After 24 hours, it has completed a full rotation of 360 degrees. The scientists used this information to divide the planet into 24 sections or time zones. Each time zone is 15 degrees of longitude wide.

What happens when you switch time zones?

When you travel to another time zone, there's a dramatic shift in your exposure to light and misalignment of your body's sense of day and night. The sudden disruption of your circadian rhythms that occurs with jet lag can be distressing, especially the further you travel.

Are time zones accurate?

Unfortunately for most, our time zones aren't determined by natural and scientifically researched phenomena.
