In traditional romance culture, anniversaries follow a predictable annual cadence: 1 year, 2 years, 5 years, 10 years. While annual anniversaries are timeless traditions, modern couples are embracing an exciting, creative new trend: celebrating exact day count milestones. Rather than waiting 365 days for the next celebration, couples are surprising each other on their 100th day together, their 500th day, their 1,000th day, or their 10,000th day of marriage.
