NHK日本語発音アクセント辞典 lists 4月 as either しがつガ{LHHL} or しがつガ{LHHH}, but is しがつ{HLL} also said?

Examples: 1, 2, 3, 4

  • I can’t believe NHK lists 平板 as correct for those month names. I don’t think I’ve ever heard it even from NHK announcers.

  • @aguijonazo It only lists them as heiban for their adverbial usage. 「4月行われる伝統行事」 Commented Jun 8, 2022 at 11:48

    @aguijonazo Ah, that's because sakura-paris is a rip of NHK 1998. The heiban noun entries were removed from NHK 2016. Commented Jun 8, 2022 at 12:44

Yes, even though NHK prescribes that にがつが{LHHL}, しがつが{LHHL}, ごがつが{HLLL}, くがつが{HLLL} are correct accent, にがつ{HLL}, しがつ{HLL} are also heard, that effectively regularize all 3-mora month names in 頭高型.

In my observation, this type of accentuation is mostly heard when the speaker refers to a specific date, presumably intending to make the number sound more salient. It is less likely to appear when you talk about, say, 『四月は君の嘘』.
