SWMBO asked me yesterday how much longer each day is until we get to midsummer and I realised that not only did I not know the answer but didn't know either how to work it out or even where to go for information. The builders of Stonehenge would have fired back the answer in a jiffy and SWMBO was quite surprised that there was something I didn't know. This must have been a shock to her as she is always telling me that I know it all.

She has already worked out that by checking the sunrise and sunset daily on her smartphone over the coming week she can find the answer. Can you help me beat her to it so I can re-assume my mantle of omniscience?
