1月19日期末了,期中时考了97分（120满）,光我们班就有许多上100的.

Zhou Runfa was born on January 19th.

从1月19日到5月19日共13+28+31+30+19=121天（闰年为122天）
从2月1日到5月19日共28+31+30+19=108天（闰年为109天）
所以甲应付电费为310÷（121+108）×121=163.799元（闰年为310÷（122+109）×122=163.723元
所以乙应付电费为310-163.799=146.201元（闰年为310-163.723=146.277元）

1、 2014年1月19号是星期日,
计算方法 ：19号+系数2=21 被7整除 即星期日
2、2014年2月5号是星期三,
计算方法 ：5号+系数5=10÷ 7= 1.3 即星期三（不够7整除属于余数）
