Um, well, both of the final points would also apply to a date of eg 16th August 2018, and that's certainly three words and is unlikely ever to be accepted as one anywhere!@The Judge and the moderators
My 2 pennies about the date: you should consider the date as one word, no matter what is chrons history with it.
Reasons:
- is a well known formatting and not an author invented one;
- it is referring to a single point in time
- it is intended to make the reading more clear, by setting the precise time of action
The fact it might be a standard format -- though to us in the UK it's more often eg16/8/18 -- is something we're considering. Stay tuned for a decision!
Meanwhile, as always, if someone is impatient to post and can't wait for a decision, always err on the side of caution -- better to have a story which feels truncated at 73 words than a perfect story which we decide comes in at 77.
