What is your take on a spouse who doesn't celebrate nor give importance to special occasions in your family even your anniversary?

When my partner and I first got in a relationship, we were so ecstatic to celebrate special occasions like birthdays, Valentine's day, monthsaries, and of course, our anniversaries. We had surprises and unique gift ideas for each other. However, as our jobs demanded most of our schedule, we seldom celebrate anymore. A date every once a week became a habit. Since we are together for almost 4 years, we do not feel any discontentment with this setting. Our treatment for our one-day dates is more than a special occasion celebration.
