Translation guide
The English word 'weekly' can be expressed in Japanese through adverbs, nouns, and adjectives. The most common way is using 毎週 (まいしゅう) as an adverb meaning 'every week'. For 'once a week', 週に一度 (しゅうにいちど) or 週一回 (しゅういっかい) are used. As a noun referring to a weekly publication, 週刊誌 (しゅうかんし) is standard.
