How to use it
In conversation a week is อาทิตย์aa-tít, the same word as the sun and as in Sunday, วันอาทิตย์wan-aa-tít; the context makes it clear. News, timetables and forms use สัปดาห์sàp-daa, which you'll also hear in careful speech.
This week is อาทิตย์นี้aa-tít níi, next week อาทิตย์หน้าaa-tít nâa and last week อาทิตย์ที่แล้วaa-tít tîi-láew. "Once a week" puts ละlá, per, after the week: อาทิตย์ละครั้งaa-tít lá kráng.
