Use regex for identifying birthday posts

This will be more efficient in handling the birthday posts. Make a stricter check on identifying which are birthday posts and which are not.

Are you sure it easily can be done by using only regex?

No I dont think regex is enough for identifying this. If we need to accurately identify the birthday posts, we will have to employ nlp algorithms. But, I dont think such high accuracy is needed here, since the script has to run only on a particular day when we don't need to filter out posts with such strictness.
Still, we can just look out for the word "birthday" or "day" or "happy" etc, to identify a post.
