which bit of the website are you using to get those numbers, because most of the time when it gives a date it means the last day in that week, so the week of 10th November also includes the days from 4th to 9th November.
ah, i see you are using the table... excellent, but still take note of what the dates mean. the numbers you posted are for the period of 5th November to 16th December.
This table starts on the 5th Nov and ends 16th December.
Of course if you start a week earlier (to include all of November, plus 3 days of October)
which shows the 360 ahead, the two have been swapping places for the last few weeks.
