这里特别推荐WeekdayName() 函数.MonthName() 函数,将日期转换为中文星期名与月份,如"星期一"."五月"一.Date() 函数.Now() 函数和 Format() 函数Select Date(), Now();Date() 函数以短日期格式返回当前日期.Now() 函数返回当前日期和时间. Select Format(Now(), "dd mmmm yyyy");您可以对日期值使用 Format() 函数来指定要用于该日

获取周的第一天,最后一天 System.out.println(getStartEndDate("2016-05-01", 1)); 获取星期的第一天和最后一天 System.out.println(getStartEndDate("2016-05-01", 0));   public static String getStartEndDate(String aDay, int type) { SimpleDateFormat df = new SimpleDate

JS获取日期时遇到如下需求,根据某年某周获取一周的日期.如开始日期规定为星期四到下一周的星期五为一周. 格式化日期: function getNowFormatDate(theDate) { var day = theDate; var Year = 0; var Month = 0; var Day = 0; var CurrentDate = ""; // 初始化时间 Year= day.getFullYear();// ie火狐下都可以 Month= day.getMonth()

本文实例讲述了PHP获取日期对应星期.一周日期.星期开始与结束日期的方法.分享给大家供大家参考,具体如下: /* * 获取日期对应的星期 * 参数$date为输入的日期数据,格式如:2018-6-22 */ function get_week($date) { //强制转换日期格式 $date_str = date('Y-m-d', strtotime($date)); //封装成数组 $arr = explode("-", $date_str); //参数赋值 //年 $year =

这是小川的第415次更新,第448篇原创 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第266题(顺位题号是1185).给定日期,返回该日期的星期几.输入为三个整数,分别代表日,月和年. 以下列值之一返回答案:{"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday

ufn_GetWeekFirstAndEndDay    获取指定日期所在星期的第一天和最后一天日期 ALTER FUNCTION [dbo].[ufn_GetWeekFirstAndEndDay](@tmpDate DATETIME)RETURNS  @tmpTable TABLE(            FirstDay DATETIME ,          EndDay DATETIME   )ASBEGIN    INSERT INTO @tmpTable    SELECT a.Fi

需求来自一个朋友:编写一个简易日历.在文本框中输入要查找的日期,程序可以计算出这一天处在该年份的第几周,并且能判断出这一天到底是星期几. 应为要有交互,选择了Js来实现,也算是 结对编程 的初试吧. 我将显示部分用html 写好,点击的按钮触发事件函数是check(): function onCheck(){ var Year = document.getElementById("year").value; //获取文本框的“年” var theYear =Year * 1; //转换

=TODAY() ="第"&WEEKNUM(TODAY())&"周" =TEXT(TODAY(),"aaaa") Ctrl + ` ="XX部门第"&WEEKNUM(TODAY())&"周周报"

不说了,对于PHPer来说,写不出来说什么都是白瞎,不喜勿喷~~~~ function get_week(){ $data = []; $format='Y-m-d'; for ($i=0; $i<7; $i++){ $strtotime = strtotime( '+' .$i.' days'); $data[$i]['date'] = date($format ,$strtotime); $data[$i]['week'] = "周" . mb_substr( "日
