微软的日历控件为什么从1753年开始？Sqlserver数据库不能插入175

很久没写日志了，最近在研究公历与农历的，在用微软的Calendar控件时候，无聊看看它最早能到几几年，惊奇的发现居然只到1753年。 原来，现行的公历是格利戈里历法，这个历法并不是连续的，中间缺少了11天。紧接在1752年9月2日的日期是1752年9月14日。 抹掉这

很久没写日志了，最近在研究公历与农历的，在用微软的Calendar控件时候，无聊看看它最早能到几几年，惊奇的发现居然只到1753年。

原来，现行的公历是格利戈里历法，这个历法并不是连续的，中间缺少了11天。紧接在1752年9月2日的日期是1752年9月14日。

抹掉这11天是由英国议会在1752年做出的决定。

而微软之所以没加入之前的日期应该是因为之前的日期混乱，各国去掉的11天日期并不统一：
