Some times for your alarm clock.

So what are you doing for the Solstice; setting fire to a Wicker Man? Or just walking up the nearest hill or tall building with a clear view of the eastern horizon. That 04:00 alarm[1] can be a challenge but it's worth it even when it's pouring with rain like it did last year in most of the UK.

[1]For bonus Gaia points, keep vigil for the whole of the previous night.
