I have been home for a while and I miss you all very much.
I remember one day Mom told me that her birthday was just one day before mine,which means it's her birthday today! Wish my Mom a happy birthday!
这是按照您的字面意思翻译的。
其实这段中文的逻辑有问题,比较乱哈。
提问者可否理清思路再表述下。
It has been a few days since I came back home,I was always missing you.I remembered that one day my mother said that her birthday is one day before mine,which is today.Happy birthday to my mother!!
【纯人工翻译,不是很地道,有不懂的可以继续问我。】
可以试着这样:
I've been home for a time, and missed you guys a lot. I remembered one day mom said it was just her birthday before mine, today is the date, happy birthday to my mom.......
