My counts of traffic activity here confirm this. Daylight saving is a way of matching our activity, which is nowadays based on artificial clock time, with the best use of daylight hours. Before clocks, this happened naturally. Of course this doesn't happen any more. Typical shop, office and university hours are usually 9 to 5.
Most people seem to prefer to get up and go to work or school, then relax in the evenings.
The workable approach to DST that Stephanie calls for would surely be achieved if we chose the start and end of DST to best suit the lifestyle of majority of Australians. For example, most people in the Eastern States are happy to keep DST until the end of March. This corresponds to a start date of September 9. The approach could be even more workable if areas in the far west of NSW followed Broken Hill in adopting South Australian time. This would also solve a major problem between city and country, that of common working hours.
