Excel表格自動(dòng)計(jì)算天數(shù)時(shí)間

在當(dāng)今的數(shù)字時(shí)代，數(shù)據(jù)已成為推動(dòng)商業(yè)決策的關(guān)鍵因素。手動(dòng)計(jì)算天數(shù)和時(shí)間不僅耗時(shí)且容易出錯(cuò)，這無疑限制了我們利用數(shù)據(jù)進(jìn)行有效分析的能力。幸運(yùn)的是，Excel提供了一種自動(dòng)化的解決方案，讓我們能夠輕松地計(jì)算和管理這些關(guān)鍵的時(shí)間單位。

Excel中的日期與時(shí)間函數(shù)

Excel內(nèi)置了許多強(qiáng)大的日期和時(shí)間函數(shù)，使我們能夠以前所未有的精確度處理時(shí)間數(shù)據(jù)。以下是一些關(guān)鍵的函數(shù)：

1. DATE: 創(chuàng)建一個(gè)日期值，表示特定日期和時(shí)間。
2. NOW(): 返回當(dāng)前日期和時(shí)間。
3. TIME(hour, minute, second): 創(chuàng)建一個(gè)時(shí)間值，表示特定小時(shí)、分鐘和秒。
4. TIMEVALUE(text): 將文本轉(zhuǎn)換為時(shí)間值。
5. DATEVALUE(text): 將文本轉(zhuǎn)換為日期值。
6. TODAY(): 返回今天的日期。
7. YEAR(date): 返回日期的年份部分。
8. MONTH(date): 返回日期的月份部分。
9. DAY(date): 返回日期的天數(shù)部分。
10. HOUR(time): 返回時(shí)間的小時(shí)部分。
11. MINUTE(time): 返回時(shí)間的分鐘部分。
12. SECOND(time): 返回時(shí)間的秒部分。
13. DATEDIFF(start_date, end_date, unit): 計(jì)算兩個(gè)日期之間的差異（以指定單位）。
14. DATEPART(year, date): 提取日期的年份部分。
15. DATEPART(month, date): 提取日期的月份部分。
16. DATEPART(day, date): 提取日期的天數(shù)部分。
17. WEEKNUMBER(date, start_weekday): 計(jì)算日期是一周中的第幾天。
18. ISOFORMAT(date): 返回日期的ISO格式表示。
19. TEXTJOIN(",",TRUE,array): 將數(shù)組中的元素連接成一個(gè)字符串。
20. TEXTJOIN(",",FALSE,array): 將數(shù)組中的元素連接成一個(gè)字符串，但不包括逗號(hào)。

使用Excel計(jì)算天數(shù)和時(shí)間

假設(shè)我們要計(jì)算從今天開始到明天結(jié)束的總天數(shù)和時(shí)間。我們可以使用以下步驟：

1. 輸入今天的日期和時(shí)間。
2. 輸入“=TODAY()”來獲取今天的日期和時(shí)間。
3. 輸入“=DATEVALUE(TEXTJOIN(",",TRUE,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(" ",1,TEXTJOIN("-",1,TEXTJOIN(""","")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24.""","")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,"")24,")24,")24,")24,")24,")24,")24,")24,")24,")))"""
