Mum and Dad's anniversary

Mum and Dad were married in the War time. They grew to love each other. Mum died on the 2nd day of the Chinese New Year. Dad died 18 years later on the same day and month. Which partially fulfills this Chinese saying.
我们不是同年同月同日生，但可以同年同月同日死 We are not born the same month on the same day, but died the same day in the same year

不求同年同月同曰生，只愿同年同月同曰死……出自三国演義。
