Sometimes we want to send email at a specific time based on where the contact is located. There are ways of finding this out through google or the post office or other one-off ways. But what if you wanted to look up several contacts/customers at once - given just a postal code and a state.
I might add, this problem is not easily solved several states have 2 time zones.
I approached this by not wanting to have a gargantuan table of each postal code to a timezone. So I made postal code ranges, reducing the set to some 427 rows, small enough to post here. Note: the time zone is X number of hours relative to GMT , so -8 is Pacific Standard Time. It also indicates if the state recognizes daylight savings.
I built a table from what I could find find from looking up zip codes.There may be some exceptions (for example the Navajo nation recognizes daylight savings, but AZ does not). So that would have to be added to, or dealt with. But by and large this could be useful as a quick look-up , just query if your postal code is within the range.
Hopefully it is accurate, if anyone finds an issue let me know.
Here it is:
