Cold dew: Wild geese come as guests (4 of 5)

April 9th, 2009

Cold dew 4 of 15A hactic week before the Easter break presented a huge back log of laundry and dishes. The end of daylight saving also means that by the time we get home it is already dark, making gardening or general outdoor activities unfeasible. The darker evenings are more inducive to going to bed early.

People often have strong feelings about daylight saving time (DST). One of the original main goals of DST is to shift the hours forward to match summer sunrise so as to encourage people to make better use of morning daylight. However, the focus now seems to be solely on the afternoon extra recreation times. The social, economical and political motives behind DST have also become very complex.

If you are far enough from the equator the lengths of the day inevitably vary between summer months and winter months. Perhaps it would be sensible to adopt different schedules for different seasons – to live by the sun. At least this is what other living things do, it’s called photoperiodicity.

    I never understand the reluctance of west australians to adopt daylight saving time. do you, jo?

    Hi Lucas,

    I thought about day-light saving and photoperiodicity for quite a bit. With the case of Western Australia, I think the state is simply too large to have one time-zone (although I think places like Ecula are actually 45 minutes ahead – but not officially). The state also stretches too far north and south for it to have day-light saving working for everyone. The closer you are to the equator, the less day lengths vary between summer and winter. It will just be a nuisance to have to put your clock backwards and forwards if you have equal day lengths of 12 hours throughout the year. In places where the difference in day lengths is marginal, day-light saving is really moving the hour from the morning to the evening – essentially, you get up earlier (probably in the dark) so you have an extra hour of daylight in the evening.

    I am personally in favor of everyone setting their own time zones. I think we are all photoperiodic: we should designate more hours for sleeping in winters.
