### 3/5 — 中段〜下段表示がされなくなった。不成就日は要らない。

*2025-01-15*

アプリアップデートしたら中段〜下段表示がされなくなった。(iOS18)

不成就日は、宣明暦時代には会津暦に記載されただけであり、貞享暦にも記載されていない。しかし、この時代から、幕府の許可なく発行された民間の暦には記載されていた。

不成就日は歴史的に根拠ない

出来ればON、OFFで表示が出来れば良いと思う。

### 3/5 — 見るには便利だけど…

*2022-11-01*

知りたい暦情報は殆ど入っているので、長年使わせていただいてます。が、記入したイベントが一覧で表示されないので見落としそう。やっぱり閲覧用がメインなのでしょうかね〜

### 3/5 — 2021年の祝日変更してください

*2021-06-28*

2021年の祝日、6月末になりましたがまだ変更がありません。カレンダーアプリとしては、、いかがなものでしょうか、、、

### 2/5 — 祝日がない。

*2020-12-11*

頻繁なアップデートがない。
令和2年・今月12月23日(水曜)は、天皇誕生日で祝日になるはずが、祝日になっていません。
制作者は手を抜いてますね、放置アプリ。

### 1/5 — 2020年9月1日(火) 一粒万倍日表示されない

*2020-08-31*

2020年9月1日(火) 一粒万倍日表示されないのはなぜ？他の吉日もたまに表示されない気がします。
購入したアプリのライセンスがこのような状況はケシカランですね

### 1/5 — 便利ですが

*2020-03-02*

九星が間違ってる
沢山の人から修正のお願いされているのに、何故直せないのかね？
これ作っている人は知識がないの？

### 4/5 — 非常に便利

*2020-03-01*

六曜、旧暦、干支等大変便利に使用させて貰っています。

そろそろ令和に対応していただけたら星５つにしたいのですが...

### 4/5 — 2019/11/23から九星がずれている

*2020-02-08*

大変便利に利用させて頂いています。

残念ながら、2019/11/23から日の九星がずれています。
2019年の隠とん→陽とんの切り替わりがその日なのですが、それが2019/12/23に設定されてしまっている様です。

また、未だ平成の表示になっており、令和への対応をお願いしたく存じます。

### 1/5 — 九星

*2019-11-23*

2019.11.23現在九星が誤表示してますよ。

### 3/5 — 令和ですよ

*2019-11-01*

お気に入りなのですが
アップデートが遅く
まだ平成のまま(◞‸◟ㆀ)
早く令和に対応をお願いします。
