I applied I-140/I-485/EAD/AP concurrently on May 21 and the receipt date for all of them was 06/01/2007.

I received FP notice on 06/14/2007 and completed the same on 06/27/2007. LUD on I-485 changed on 06/28/2007 followed by another change on 06/30/2007 (A saturday).

Any idea why they would be updating my file on a Saturday? I heard rumors that USCIS folks were at work over the weekend checking the visa number availability. So I am wondering why they updated my file. Anyone else have the same change to your LUD on I-485?
 
I had my fingerprint done on 6/14, and got an LUD on 6/16 (also a Saturday). I am wondering if the date stamp of the LUD reflects a true instant update. Maybe they did an update on Friday, and the system auto patched in on the following Saturday. But I do hope they work on weekend though.
