24 alternatives to Timezone converter that tells you if your meeting time sucks

I work with a team spread across Sydney, London, and SF. Last month I accidentally called my Aussie colleague at 3am their time during what I thought was a "quick sync".

Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so.
