A fortunate person has good things happen to them by chance or luck.
When we say someone is fortunate, we usually mean that they've had some lucky breaks. For example, maybe they won a big prize in a contest, got a great new job offer, or met their future partner at the right time. We also use this word when talking about good things that happen to people who are trying very hard to achieve something - like athletes who get ahead after years of training and perseverance. In general, fortunate is used to describe someone whose path has been smooth and successful.
Auspicious.
Example: It is a fortunate sign if the sun shines on a newly wedded couple.
