Your Red (and Green) Flags, Based on Your Birth Month

Having a clear understanding of what the red and green flags mean can be a lifesaver when building relationships. Knowing where and who to put our attention is pivotal, especially when we are defining relationships and partnerships. It's easy to lean into the vibe of the month's astrology to find how we connect and align with others, as well as our triggers and needs. It is an excellent way to weed out people who don't have our best interests at heart and bring others who exhibit amazing qualities into our lives. However, we all have our strengths and weaknesses. What we find is that a red flag may be a neutral or good character trusted by another. Read on to discover what each birth month will most likely consider a green flag in others, versus a red flag.

What are red flags?

In the realm of dating and friendships, red flags serve as warning signs that reveal a person's true character. For instance, if someone behaves rudely or aggressively toward wait staff, that is a red flag. It's important to pay attention to these signs to avoid potentially problematic situations.
