This counter answers

When Each Question Has to Be Asked

The most useful thing on this site for somebody short of time, and the only line on the worksheet that is about the calendar at all.

The four fields

What the hold asks: For each line on the worksheet, how late can it still be put to a lot and get a useful answer
What comes back: A deadline per line, set by how long lots actually take to reply rather than by anything this counter would prefer
When to ask: Now, before the request, because two of the eight lines are already closed by the time most people start looking
If it is not asked: The question goes out anyway and the quote records that it went out late and got no answer, which is a worse outcome than knowing in advance

The deadlines

The line	Still worth asking	Why it closes when it does
The perimeter, in the lot's own words	Up to the day before	It is a standing description and a lot can send it at any time
The shuttle timetable	About three days ahead	A lot will confirm a current pattern quickly; confirming a pattern for a future month takes somebody to look
Access after a clearance run	About a week ahead in winter	The people who can answer this are the people clearing ground, and in a heavy week they are not at a desk
The day rate if the return slips	Any time, including after you travel	This counter writes it, so it has no deadline
What the written quote contains	Any time	Same reason
Whether a roof stays free	No deadline, because no answer comes	It is in the silent group
Whether anyone is there at night	No deadline, same reason	It is in the silent group
An outlet within reach	About a week ahead	Only a few lots have one at all, and finding which takes asking several

Why this is not a calendar

This counter deliberately does not organize itself around the calendar, because that is how another desk is arranged and repeating it would be a worse version of something already done well. The dates above are deadlines attached to questions, not a structure. There is no month by month table on this site and no stretch of dates here moves a price band.

What the dates do is stop the commonest disappointment: somebody asks a good question two days before travel and the answer arrives after they have gone.

The two lines that are already shut

By the time most people start looking for parking, the two silent lines have not become answerable. They will not. They are printed on the worksheet so that nobody spends a week chasing them, and the page for them says why in full.

If you are inside the deadlines

Then the useful order is: ask everything at once, take the quote, and decide from the answers plus the unanswered list. Splitting the questions over several days produces several partial quotes and no clearer picture.
