EXCEL VBA 他 時間計算 時間シリアル 十進数変換法

  • 表示形式のテクニック
  • 2017/1/24更新しました(C43の式が間違っていたののほかA50以下の解説追加、参考リンクの追加)
  • 2017/1/25更新しました(解説、換算式の追加)2017/1/25更新(負の時間、式内の時間)

  • セルに入っている数が整数かシリアル値かで違う(C6)
  • 時間(hour)を表す整数なら24で割って足す(C6)
  • 時間(hour)を表すシリアル値ならそのまま足す。(C7)
  • ここで演算誤差が発生することが理解できる。
  • 見た目が似ていても本当の値は違う。
  • 整数値にする場合、小数点以下を表示しないがドットが残る表示形式か、条件付き書式で区別できる

何時間か(差)
時間を長整数型にするE2
引いて*24でRoundする

excelはマイナスの時間を扱えない

  • マイナスになる計算をさせるとエラーになる(C58)
  • 1904オプションを有効にすると解決できるが、普通はやらない。なおこのオプションを有効にしてもマイナスの時間を入力することはできない。
  • 絶対値で計算させるとできる。ただしセルの内部は正のシリアル値になる
  • マイナスの時間はオプションを変えても有効に入力すらできない。

セル内の数式内部の時間(64行目から67行)

式内部での表記は二重引用符で囲み”09:00"or”09:00:00"と書く

そのうえで*1としないと文字列として扱われる。

'=IF(A66>="9:00:00"*1,TRUE,FALSE)

換算、変換のテクニック

関数を使う

TimeValue関数を使う

Time関数を使う

=Time(16.50,21)という形で1日にのうちの時刻を示すことができる。

定数で換算する

十進数から時間(シリアル)にするには以下の数で割る(B38~B40)

時間にするのが24
分にするのが3600
秒にするのが86400

十進数から時間(シリアル)にするには以下の「数」を乗じてもよい(C38~C40)

時間にするには("01:00:00")をかける
分にするには("00:01:00")をかける
秒にするには("00:00:01")をかける

文字から時間、十進数とシリアル値の変換は表示形式や定数で乗除して行う

時間から時分秒に換算

Hourなどの関数を使う。ただしこの関数はそれぞれの最大値が24,60,60を超えてはならない。
さらにそれを換算定数で乗除して十進数と時間シリアル値の換算ができる
時間にするのが24 
分にするのが3600
秒にするのが86400
または時間は十進数を"01:00:00"で割ってもよい(C51)
=1/”00:01:00”とすると1分のシリアル値が求められる

1600分は何時間か

=INT(A18/24)&":"& MOD(A18,60)
24で割った数が時間 60で割った余りが分

24時間を超えるか超えないかで違うこと

和が24時間を超える場合は表示形式を変える

With ws.Range("\$C$13")
.Formula = "=SUM(C10:C12)": .NumberFormat = "[h]:\mm:ss"
End With

表示形式で小数点以下を表示するかしないかがかえられる

ユーザー定義(G3)ドット(小数点が残ってしまう)
条件付き書式(H3)小数点は残らないが、設定方法が複雑

VBAのコード

基本的な変換

文字列から時間へ

CDateで囲む

CDateで囲むと時間になる
Cdate(“01:00:00”)

リテラルで時間だけ囲む

リテラルで時間だけ囲むと時間になる。
#01:00:00 PM# #13:00:00# どちらでもよい
#01:00:00 PM# = Cdate(“13:00:00”)
1日うちの何時かはTimeValue関数を使う
TimeValue(“01:00:00”)
TimeValue("01:22:01 PM")

TimeSirialを使う

TimeSerial(2,200, 300)
-32,768 ~ 32,767の数を使える
合計がマイナスにならない限り、マイナスの値、マイナスになる数式も使える。24時間を超えると0元に戻る。
?TimeSerial(8,-200, 32000)
13:33:20
