Pagerank is updated roughly every 3 months. An update happened around February 9th, and again around May 3rd. I expect the next update sometime in early August.
Usually page rank update take place after 3 to 4 months, wait untill that...hope everyone will receive good news. Thanks
google updates PR 4 times a year. But it's only about a PR whole table of sites. Practically, PR for a certain site can change at any time, but you won't know about this, because the number stay the same (old). This shadow PR affect rankings though
