求解at the open day(为何不用on the open day)

下面的句子摘自牛津高中英语模块一第9页:
Next month it will be our annual school open day.We have invited David to be one of our guest speakers.He will make a speech about his experiences in China.The speech is going to be at 3 p.m.on 9 November.At the end of his speech,there will be 30 minutes for questions and answers.So,if you are interested in knowing more about China, you mustn’t miss the chance to meet David at the open day.
我对最后一句中的 at the open day 不理解,为什么用介词 at 呢?在某一天不是该用介词 on 吗?这里可以改用 on the open day 吗?
另附:我在词典上查了一下,open day 是个短语,意思是“(学校、大学或其他机构的)开放日,接待日,参观日”,词典的英文解释是:An open day is a day on which members of the public are encouraged to visit a particular school, university, or other institution to see what it is like.(注意英文解释中用的介词 on)

So,if you are interested in knowing more about China, you mustn’t miss the chance to meet David at the open day.

参考译文所以,如果想更多了解中国,在我们的开放日(活动期间),你一定不要错过见见大卫的机会。

参考解析这句话是正确的。难在at的特殊用法。At通常指时间点,但有时可指时间段,尤其是与Christmas/ Easter以及当open指某种【公开性活动】时,表示【在此段/活动期间】。比较:

at  the open day 在开放日(活动期间)

on the open day 在开放日(那天)

at Christmas (time)  在圣诞节期间(不单指1225号这天,指整个圣诞季)

on Christmas day 在圣诞节那天(指1225号)
