When you’re browsing Tumblr, you’ll see a lot of blogs with clearly dated content. For example, if a blog was published in 2013, you’ll likely see posts about current events from 2013.
If the blog was published in 2018, posts about current events from 2018 will be more prevalent.
Tumblr does this to help users keep track of the time period in which a blog post was written. However, it’s not always possible to determine the exact date a blog was published.
In some cases, the date may be obscured by metadata or by the design of the blog itself.
If you’re trying to determine the age of a Tumblr blog, it’s best to look for clues in the content and design of the blog. However, it’s sometimes difficult to determine an exact date.
In those cases, you can use other methods to estimate the age of a Tumblr blog.
