Revision as of 17:13, 28 September 2006
Details of the countdown
After some math and testing with Flash, I calculated that the oculus has an alignment period of:
- 1 day, 20 hours, and 48 minutes exactly
Which means, given it aligned at 11am, Sept 28, 2006, the next 'on the hour' alignment will be 5 periods from 11am, or every 9 days and 8 hours... which means further alignments will occur on the hour on:
- Sat, Oct 7, 7pm (12am, Oct 8, GMT)
- Mon, Oct 17, 3am (8am, GMT)
- Wed, Oct 26, 11am (4pm, GMT), etc
So, here's the summary... The oculus will align:
- Every 1 day, 20 hours, 48 minutes
- Every 9 days, 8 hours - on the hour
- only on the hours 7pm, 3am, and 11am (Eastern)
- only on the hours 12am, 8am, and 4pm (GMT)
- Every 28 days (4 weeks precisely) on the same hour
Visually... apply this diagram to a calendar:
The times noted are when alignment occurs on the hour (for each timezone) By this diagram, you can apply Sept 28, 11am to the thursday instance. Oct 7, 7pm is the following saturday (9 days and 8 hours hence).
There are many other times when alignment will occur, but each of those is not on the hour. So, if you want to calculate every instance of an alignment, as mentioned above, it occurs every 1 day, 20 hours, and 48 minutes (so add any number of those periods to any hourly instance from the diagram above, and you'll have an alignment day+time)
