Eight in Japanese is 八 which looks similar to katakana “ha” ハ and jas the readings ハチ(hachi)　ハツ(hatsu)　や(ya)　よう(you) Dates are usually written as 8月8日(8th month 8th day) though and the only onomatopoeia for stomach growling I can find is ごろごろ (gorogoro). Am I too stupid to get this? I can’t see how the date 8/8 resembles the noise of a rumbling stomach
