We celebrate our anniversaries because we want to honour our time together, because we know that maintaining a relationship is not an easy task and because love is all that really matters in life. Traditionally, it's a celebration of our wedding date but it can also be an anniversary of our first date or the day we've got engaged. However, an anniversary does not just have to be about a relationship. An anniversary can also celebrate our time at a particular company, the beginning of starting a business, or even the anniversary of our favourite sports team's championship game.
