So my traditional catholic calendar had ember days as last week, but my parish bulletin has it as this week... I am confused.

In the Roman rite the September Ember Days were always kept on the Wednesday, Friday and Saturday after the feast of the Exaltation of the Holy Cross. In the Breviary this was the third week of September.

As G.B. notes above the 1960 rubrics, which came into force on 1st January, 1961, changed the way the first Sunday of the months of August, September, October and November was calculated. In the traditional system the first Sunday was that closest to the 1st of the month so, e.g. this year, Sunday 31st August isconsidered the first Sunday of September. In the new rubrics, R.G. Ch. III, 19, this was changed so the first Sunday always was counted in the actual month.  So, the first year this would have made a difference to the Ember Days was 1964. In the new system the Ember Days were kept on 23rd, 25th & 26th, a week after they would traditionally have been kept.  It may be the case the reformers didn't consider the effect the rubric would have on the Ember Days.
