아빠의 생일 파티

We have a dedicated term for the 60th birthday: "환갑"

It means so much in the Asian culture because of "간지"

https://en.wikipedia.org/wiki/Sexagenary_cycle

10간:

갑을병정무기경신임계

12지 (The animal belt):

자축인묘진사오미신유술해

Each year gets one of 간 and 지 assigned and both advance (and eventually cycle) by one per year.

2017 is "정유년" and 2018 will be "무술년" (by moon calendar of course)

And the least common multiple of 10 and 12 is 60.

Which means that there are 60 possible combinations of both cycling through.

Your father was born in "정유년" sixty years ago and 2017 is the first "정유년" after his birth which makes this birthday of his so special.

우리 아빠의 생일 파티

다음 달 우리 아빠가 예순살일 거예요.(Next month my Dad must be turn 60-year-old.) Therefore,  it's not proper.

우리 가족은 아빠에게 놀라운 생일 파티 하겠어요. (Our family will have a surprise birthday party for my Dad.)

저는 생일 케이크를 굽겠어요. (I will bake the birthday cake.)

이 생일 케이크가 화려하게 보이고 엄청 맛있어야 해요. (This birthday cake will need to look amazing and taste very delicious.)

이제 저는 조리법을 많이 연습하고 있지만,  조리법 중에서 하나를 고르는 것은 너무 힘들어요. (I am now trying many recipes but it is hard to choose only one recipe.)

In Korean, recipe is translated 조리법. But now in Korea, 레시피 is more natural. 

저는 우리 아빠가 생일 케이크를 정말 좋아했으면 좋겠어요! (I hope that my Dad really really really likes his birthday cake!)
