Example 1: Python Add Months to Date main.py from datetime import datetime from dateutil.relativedelta import relativedelta myDateString = "2022-06-01" myDate = datetime.strptime(myDateString, "%Y-%m-%d") addMonthNumber = 2; newDate = myDate + relativedelta(months=addMonthNumber) print("...

from datetime import date # 创建一个日期对象 d = date(2024, 4, 15) # 表示 2024 年 4 月 15 日 # 获取当前日期 d2 = date.today() # 访问日期对象的属性 print("年份:", d.year) # 输出: 2024 print("月份:", d.month) # 输出: 4 print("日期:", d.day) # 输出: 15 print(d)...
我们用下面的代码来实现: defadd_months(start_date,months):# 计算新的年份和月份new_month=(start_date.month-1+months)%12+1new_year=start_date.year+(start_date.month-1+months)//12# 找到新的日期new_day=min(start_date.day,(datetime.datetime(new_year,new_month,1)+datetime.timedelta(days=31...
一、提取日期(year,month,day,hour,minute,second函数) 案例1:提取日期中的年,月,日,时,分,秒。 二、组合日期函数(Date函数,Time函数) 案例1:组合日期 案例2:使用date函数与文本提取函数生成完整日期 总结: Date函数作用为将年月日,合并在一起,成为一个完整的日期格式。
DATEVALUE(date_text) DATEVALUE 函数将存储为文本的日期转换为 Excel 识别为日期的序列号,里面只有一个参数,也就是文本格式的日期,例:把文本格式的单元格转化为日期格式,然后可以把44954变成日期显示 EOMONTH(start_date, months) 返回某个月份最后一天的时间序列号,EO是英文end of的首字母缩写,end of month也就是...
start = date(2019,1,1) # 设置个月份递增的函数 def add_month(d,md): y = md // 12 m = d.month + md % 12 if m !=12: y += m // 12 m = m % 12 return date(d.year + y, m,d.day) for i in books.index: books["ID"].at[i]=i+1 ...

Therelativedeltaclass is very convenient because a month can have different days. If you use thetimedeltaclass, you need to calculate the different days each month has and sum them yourself. 4. Adding years to a date in Python To add years to a date in Python, you can use thetimedeltaor...
