開店 and 閉店: daily opening and closing, and a new shop opening
Distinguish daily opening times from a new shop launch, interpreting closing notices with their dates and repetition.
Opening for the day
開店, read かいてん, means opening a shop for business. 毎日九時に開店します。 announces opening every day at nine.
開店前から客が並んでいました。 says that customers were already lining up before opening. Check the order of arrival and the start of business.
Ending business
閉店, read へいてん, means closing a shop. 本日は午後八時に閉店します。 announces that the shop closes at eight this evening.
閉店までに買い物を済ませてください。 asks customers to finish shopping by closing time. It gives a completion deadline rather than asking them to keep shopping throughout the period.
A new shop and the context of closure
来月、新しい店が開店します。 says that a new shop will open next month. 開店 can refer both to daily opening and to a new shop opening for the first time.
この店は来月閉店します。 can occur in a notice of a shop ceasing operation. Read the date, daily repetition, next business day, and other information to distinguish daily closing from ending the shop's operation.
Does 毎日九時に開店します。 mean a new shop is established every day?
Show the answer and why
No. Here it announces that the same shop opens for business at nine each day.
