Discussion on Google PR Value Update Time

It's impossible to be very precise about the timing; it's just a rough estimate, but it still has some basis in reality. Based on my observations of several websites, both personal and company-related, I have deduced that the deadline for data collection before this PR update was around mid-February. You can also use this information to make an estimate for your own website: Among my multiple websites, many secondary pages still have a PR of 0. The vast majority of these pages with a PR of 0 were uploaded or created after mid-February. This helps to confirm the deadline for data collection before the PR update. Since we already have a rough idea of when the data collection ends before a PR update, we can infer that the deadline for data collection before the next PR update should be after mid-February, and the PR refresh time could be around mid-May (because the Google team once hinted that after adjusting the new algorithm, PR updates would likely occur once per quarter).
