Ed: Although we at AH do not believe that our Rapture is Ascension Thursday, we do believe "Ascension" is a valid word for the Rapture.
Therefore we can deduce that perhaps Lag Boemer is an indication that WHENEVER the rapture takes place, we will have a 7 day notice.
Just a thought. Noah was given a 7 day day notice before the ark ascended. Genesis 7

From my own perspective, the deaths of the students ( plague) during this period appear to me to be a judgement of asymmetric - religion ( deviating from Scripture, and getting into mysticism ).
That is just my opinion.
The 33rd day -- the remission of the plague -- reminds me of what Habakkuk said,
"O God in wrath remember mercy". Truly, He does not treat us as our sins deserve.

Lag Ba Omer 2006 -- Arutz Sheva
Israel's Chief Rabbi Yona Metzger, in his work B'Maagalei HaChayim, notes that the custom of playing with bows and arrows on this day is "apparently because tradition tied this date with the Bar Kokhba rebellion." One tradition has it that Rabbi Akiva's students were the main force of Bar Kokhba's army, which succeeded in defeating both Roman legions that were then in the Holy Land, restoring Jewish independence for four years, and - according to many - beginning to rebuild the Holy Temple. For more on the "failed Messiah" Bar Kokhba, the spiritual/military war for independence, and Rabbi Akiva's role in these events, see this article by Rabbi Pinchas Stolper of the OU and NCSY
The government recently decided to make Lag BaOmer a national day honoring IDF reserve soldiers, in appreciation for their motivation and willingness to "share the load." This will be the third year that soldiers serving in reserves on this day receive free rides on Israel Railways
LAG BaOMER IN MERON from Arutz Sheva -2003
Thousands of people have already gathered at the gravesite of the Mishnaic sage Rabbi Shimon bar Yochai in Meron, in northern Israel, for the traditional Lag BaOmer celebrations this evening and tomorrow. The celebrations began this afternoon with the traditional parade of Torah scrolls from the home of the Abu Evron family, in the Old City of Tzfat, towards Meron. Rabbis, residents of Tzfat, and visitors young and old from all over the country took part in the 170-year-old tradition.
The minor holiday of Lag BaOmer - the 33rd day of the Omer period - is marked most notably with traditional bonfires throughout the country. It marks the anniversary of the death more than 1,800 years ago of Rabbi Shimon, whose teachings comprise the text of the primary Kabbalah sourcebook, the Zohar. The bonfires - a tradition kept by Jewish children of all backgrounds in Israel - are said to represent the light of Torah
