Islam has laid down the rules of earning by Halal (lawful) means and spending in Halal way. Islam also dislikes snobbery. It also dislike useless activities.
However, celebrating Anniversaries is not Haram in Islam. Islam respects the culture of different nations.
If it is following the culture of Christians or Jews or any other religion, it is disliked by The last Prophet Hazrat Muhammad (may peace be upon him). A Muslim's celebration is worship of Allah Almighty and offering Nawafil - Prayer and thanks giving - Shukrana.
