I am using version 0.7.2 of „A Year Before“ and love it. It is a great and useful plugin. There was one issue I came across. It deals with posts that I imported from blogger. It seems that their post_date_gmt was stripped and was set to „0000-00-00 00:00:00“ This causes the post to be found but to show up as 31 December 1969. Just wanted to let you know because it could be easily fixed by checking for that and using post_date instead. Thanks again for all your hard work on this plugin!
