Feeling Lost? It’s 4-8-15-16-23-42 day

The year was 2005 - everyone was singing along to James Blunt, a new Batman franchise was about to arrive, and everyone was super excited about cryptic, mysterious TV show Lost.

Now, ten years later, shortly after 4pm on the American date system, it will be 4-8-15, 16:23:42.

If those numbers sound familiar, it's because they're the maddening, never-quite-explained digits from the show, which changed the life of Hurley, one of the main characters, and seemed ever-present on the mysterious island - from the countdown clock of season two to "the hatch".
