Coincidence or more of ja's premeditation???

Jodi Arias murdered Travis Alexander on the exact day, the same month, years later, that Travis Alexander had his first date with his ex-fiancee, Linda Ball. Is it a coincidence that ja picked that month and day to murder TA on? Did ja pick that day because as a woman scorned, she hated that TA had never proposed to her and she decided to murder him on the same month and day that him and his ex-fiancee had their first date on??? ja stole the engagement ring that TA wanted to give to Linda Ball. 

Linda Ball (TA's ex-financee) and TA had their first date on June 4, 2001.
