Hey Ennairda - since you and Nek and Lihp (because he happened to be there) were asking...
It's 620 days from the day I was born to the day my sister was born.
That's 1 year, 8 months, and ten days.
Or for you parents out there that's 19 months and 10 days.
Which is equal to about 53,568,000 seconds, or about 892,800 minutes, or around 14,880 hours. Give or take-ish.
Don't worry, these calculations were not done through the scientific genius of Annamath. Rather I used the time and date duration calculator.
I don't know why, but I like that calculator very much...
