This video presents an interesting topic for me. I hope others see it and investigate the topic themselves.
Dates which may be important. Times below are based in Jerusalem.
The Calendar used in the Bible seems to have leap months on a 19 year recurring cycle. These years are the 3rd, 6th, 8th, 11th, 14th, 17th and 19th years. This is what is known as the metonic cycle. It has been put forward that the current Jewish Calendar is not on the correct cycle, which may be a possibility and needs further investigation.
When using the Calendar, for example from Worldslastchance.com, you discover that they are in the 9th Cycle. The reason for this is as follows:
At the Fall equinox, the sun rises due east and sets due west. Immediately following the Fall equinox, the sun apparently begins moving south, rising and setting further south each day, until it reaches the most southern point in its circuit at the Winter solstice3. Immediately following the Winter solstice, which is the shortest day of the year, the sun apparently begins moving back towards the north. On the day of the Spring equinox4, the sun will again be perfectly aligned with the equator. One this day, the sun will again rise due east and set due west; day and night will essentially be the same length, each consisting roughly of 12 hours. It is only after this point that that the daylight hours will begin to outweigh the dark hours, and the sun can be rightfully said to have begun a new circuit, or revolution. For this reason, the New Year begins with the first lunation after the vernal equinox in the Northern Hemisphere5.
They have calculated that the Jewish Calendar is out for this reason. According to their calendar an extra month is added in the metonic cycle 8 which occurs on March 21 2015 and is complete on the 18th of April 2015 (29 days).
How might this fit the 2550 days?
13/10/2015 according to WLC’s calendar (which is just after the last blood moon and solar eclipse) is the Feast of Tabernacles. Seven year later the Day of Atonement is on the 05/10/2022. The number of days between? 2550!
I also note the following:
1260 days from the 13/10/2015 is the 25/03/2019. Personally I believe the two witnesses will be killed on this date. If they are killed half way through the 1260th day, three and a half days later brings us to the end of the 28/03/2019. The end of the Sabbath on the 28th.
Anyway, these are all just thoughts. I am not certain of them, but at least I know to look.
