What is the best time to plant zoysia grass?

Hello there, I'm curious about something regarding gardening. I've heard zoysia grass is a great addition to a lawn, but I'm not sure when the best time to plant it is. Could you please elaborate on when the ideal time of year or season is to sow zoysia grass seeds or plant zoysia grass sod, and why that particular time is considered the best? Additionally, are there any specific conditions or factors I should consider before planting zoysia grass to ensure its healthy growth and establishment? Thank you in advance for your insights.
