Found this on another website. I know the website is not the favorite among some here, but one thing they do is to provide the Prayer Group's messages, which are usually very simple.

Note this was a custom search so it may not work. I searched under January and got the following for 2001 and 2000:
January 1, 2001
On January 1st, the first day of the New Year, during Marija’s regular apparition at 5:45 p.m., Our Lady made a special request of Marija. She asked Marija to go up to Apparition Hill that night for an apparition at 10:30 p.m. It has been a long time, even years since Our Lady has asked Marija to go up one of the mountains. Even more special, Our Lady asked this of Marija on the very first day of the new millennium in the New Year 2001. This signifies a certain importance. A call to the mountain on the first day of the new millennium, the second apparition in the same day, to give an important message, a message Our Lady signified She wanted heard by setting it up out of the context of the normal apparition time, asking Marija to come to a second apparition. Our Lady appeared to Marija at 10:30 p.m. Marija said that Our Lady came with five angels. During this special apparition Our Lady gave the following very important message:
"My dear children, now that when satan is unchained, I desire you to be consecrated to My Heart and the Heart of My Son Jesus. I bless you with my Motherly blessing."

Marija visited a near-by orphanage in Citluk. The orphanage cares for more than 90 children and is managed by Sr. Josipa. The children, knowing Our Lady would be with them during the apparition on this day, prepared special songs to sing to Our Lady, which they did, while Marija was in ecstasy. After the apparition, Marija was happy to tell the children that Our Lady had listened to them, smiling tenderly while they sang. Our Lady looked at each of the children attentively and blessed them. Our Lady stayed a long time and gave the following message:
"I am the Queen of Peace, and I am also your Mother. Don’t forget that I am your Mother and I love you."

Mirjana had her monthly apparition of Our Lady. It was held at the Cenacle where a large crowd gathered. Our Lady gave the following message:
"Never as much as today, my heart is begging for your help! I, your Mother, am begging my children that they help me to realize what the Father has sent me for. He has sent me among you because His love is great. At this great and holy time in which you have entered, pray in a special way for those that have not experienced yet the love of God. Pray and wait!"
I have no idea of the legitimacy of what this guy in the video is saying and I am very skeptical of anything outside of Medjugorje that is proclaimed just because it is my nature to be so. I just wanted to see what I could find for messages related to the dates he mentions, and the above was the closest I could find. It still seems that the 2001 message matches more closely especially in light of his comments that it was out of the norm.
Hope that helps.
