STC89C52单片机，用C语言编程温度报警器。
万年历只是一个计时器。添加一个液晶显示屏用于显示。
应该都是在线的。你可以搜索一下。
我为你搜索了一个万年历程序。
一、阳历算法
具体算法见函数void get_solar_day_date(void)，从而确定阳历的周排列方式。
表1:
变量定义:
公共:
无符号int temp _ total _ day
无符号字符gc _ solar _ calendar _ year
无符号字符gc _ solar _ calendar _ month
无符号字符gc _ solar _ calendar _ date
无符号字符gc _ lunar _ calendar _ year
无符号字符gc _ lunar _ calendar _ month
无符号字符gc _ lunar _ calendar _ date
无符号字符start _ day _ of _ week
描述:函数get_solar_day_date(void)的输入变量是gc_solar_calendar_year和gc_solar_calendar_month。
输出变量:start_day_of_week和temp_total_day
Void get_solar_day_date(无效)
{
无符号字符temp 01；
/* -计算当前年月日是星期几。Mon ~孙？- */
/*条件初始化执行两次，以减少运算数据量。temp_total_day是一个整型变量*/
start _ day _ of _ week = 2；temp _ total _ day = 0；计算_温度= 1；
if(GC _ solar _ calendar _ year & gt；99)
{ start _ day _ of _ week = 6；计算_温度= 100；}
for(temp 01 = calculate _ temp；temp 01 & lt；gc _太阳历_年；temp01++)
{ if(temp 01% 4 = = 0){ start _ day _ of _ week+= 2；temp _ total _ day+= 366；}
else { start _ day _ of _ week+= 1；temp _ total _ day+= 365；}}
for(temp 01 = 1；temp 01 & lt；gc _太阳历_月；temp01++)
{开关(温度01)
{case 1，3，5，7，8，10，12:start _ day _ of _ week+= 3；temp _ total _ day+= 31；打破；
情况2:如果((GC _ solar _ calendar _ year % 4)= = 0)；& amp(gc _太阳历_年！= 200))
{ start _ day _ of _ week+= 1；temp _ total _ day+= 29；}
else { start _ day _ of _ week+= 0；temp _ total _ day+= 28；}破；
案例4，6，9，11:start _ day _ of _ week+= 2；temp _ total _ day+= 30；打破；}}
start _ day _ of _ week % = 7；
/*-算完当天是星期几(Mon~Sun？)和总天数- */
}
二、农历算法
2000年需要200 × 2 = 400字节，农历压缩数据表lunar_calendar_month_table[]如下。
const charlunar _ calendar _ month _ table[]= {//从农历1900到2100。
/*每个月的总天数指针*/
月份123456789 1011112
闰年31 29 31 30 31 30 31 31 30 31
非闰年31 28 31 3031 3031 31 3031。
/*从1901~2100*/
/*(0110)11000001(0110)闰月，11000001

一种确定阳历日和阴历日对应关系的算法:
对于阳历日和阴历日之间的任何其他对应关系，可以通过以下算法得到结果。具体算法是通过例如get_lunar_day(void)来实现的:
描述:函数get_lunar_day(void)的输入变量是gc_solar_calendar_year和gc_solar_calendar。
输出变量:gc_lunar_calendar_year，gc_lunar_calendar_month和gc_lunar_calendar_date。
Void get_lunar_day(void)/*计算输入的阳历年和阳历月，对应阴历时间阳历月的第一天年、月、日*/

阳历日与农历节气的对应
压缩节气数据表:
根据规律可以得到四个数据表(每个节气月有两个节气，每个节气需要两个数据表):
