Abstract
1958 to 30 December 2005. Three principal calendar effects – day-of-the-week, day-of-the-month and month-ofthe- year – are examined separately and jointly using parametric tests of differences in means and variances and a regression-based approach. The results indicate that the Australian market is characterised by seasonality of all three forms, with Tuesday, December and the second day of the month among the most significant. However, there is also evidence of structural change in these relationships, with indications that the market has become more efficient in recent years, with day-of-the-week and day-of-the-month effects becoming less important in the post-1987 crash period.
