Question: how is the date written in us?
Answer: Sometimes, a date is written in long form, like this: Sunday, June 28, 2015 (note that there are commas after the day of the week and the day of the month, but there is no comma after the month). Sometimes, a date is written in numerical form, like this: 6/28/15 or 6/28/2015 (month/date/year).
