For everyday calm and uneventfulness the neutral choices are 「平穏」 and 「無事」; 「平和」 is the broadest word for peace, 「安らぎ」 for peace of mind. The remaining near-synonyms — 「安穏」「静謐」「安泰」「安寧」「康寧」「天下泰平」「昌平」「静穏」「太平」 — belong to written prose with narrower senses, and 「落ち着き」 is about composure. Opposites: 「危険」「不安」「混乱」.
