Time Zone Management

I spent last week in Utah on Mountain Time and I found myself booking meetings in Europe, NYC, and the Bay Area regularly. I am certain that some of those meetings and resulting calendar entries are going to be wrong, wreaking havoc on me and multiple executive assistants. For some reason the cognitive load of managing multiple time zones in my head is really hard for me. I’ve gotten pretty good at doing the EST and PST thing and can do that in my head without much work. But once I get into three or four time zones at the same time, I can’t keep it all in memory.

I’m curious if there are any tricks, apps, or approaches out there for this sort of thing. I use google calendar on web and iPhone and I’m not moving away from that to solve this issue. So if the solution is to move to a new calendaring app, I don’t think I can go there right now.

But a companion app to google calendar that makes scheduling multiple time zone events would be awesome for me. Does such a thing exist?

And yes, I do have an executive assistant. She is awesome. But sometimes I need to schedule things in real time, or it is personal business which I don’t offload, or it’s something with friends which I also do myself. So while I don’t do a ton of my calendar and scheduling work, I do enough of it, usually on the go on my phone, to make this a problem worth solving. And maybe some of you struggle with this too and are looking for a solution.

So with that, any ideas or suggestions?
