Airport Parking Charges Explained: Calendar Days vs 24 Hours
Have you ever booked airport parking for what felt like a short trip, then looked at the price and thought, "Wait, why am I paying for four days?" You are not alone. It happens to a lot of travellers, and most of the time nobody has done anything wrong. It simply comes down to how the parking company counts a day. That sounds like a boring detail, but it can make a real difference to what you pay, especially if you fly at awkward times.
Two Ways to Count a Day
There are two common ways a car park can count your parking time. The first is by calendar day. Every date your car is in the car park counts as a day, so it does not matter if your car arrives at 11 PM or leaves at 6 AM. If the car is there on that date, you pay for that date.
The second is by 24 hour period. Your time starts the moment you drop off the car, and one day means 24 hours from that exact time, not from midnight. Both methods sound similar, but in practice they can give you very different totals.
A Simple Example
Let's say you drop off your car on Friday at 6 PM and collect it on Monday at 5 PM. If the car park counts calendar days, your car was there on Friday, Saturday, Sunday and Monday. That is four days. If the car park counts 24 hour periods, your car was there for 71 hours, which is just under three full periods, so you pay for three days. Same trip, same car, and one extra day of cost simply because of how the time is counted.
Why This Happens So Often
Flights rarely leave at neat times. Lots of people fly out late in the evening or come home early in the morning, and those are exactly the times when calendar day counting hurts most. If you drop off at 9 PM, calendar counting charges you a full day for those last three hours. If you collect your car at 7 AM, you pay another full day for those first seven hours. That is two days you barely used. With 24 hour counting, those short edges do not turn into extra days on their own. You pay for the real time your car was parked.
What About Going Over?
It is worth being honest here. With 24 hour periods, if you go past the end of a period, a new one starts. Using the same example, if you collected the car on Monday at 7 PM instead of 5 PM, the total would be 73 hours. That is just over three periods, so it would count as four days. This is fair, and it is easy to plan around. When you book, think about when you will actually collect your car, not just when your flight lands, and leave time for baggage, passport control and the walk from the gate.
How to Check Before You Book
When you are comparing airport parking prices, do not just look at the daily rate. Look at how the days are counted. Enter your real times, not just dates, because if a booking form only asks for dates, the price may be based on calendar days. Look at the final total rather than the daily rate, since a cheaper daily rate can still cost more overall if you are charged for an extra day. Read the small print for words like "per day", "per night" or "per calendar day". And if you are not sure, ask. A good parking company will explain it in one sentence.
How Dublin Valet Park Counts Your Time
At Dublin Valet Park, billing runs on a real 24 hour rolling window, calculated from your exact drop-off time to your exact collection time, not a calendar date. So if you drop off your car on 11 August at 11 AM and book for one day, your booking covers you until 10:59 AM on 12 August. You enter your drop-off and return times when you book, choose between Standard and Premium Meet and Greet, and the price you see is worked out from those real times.
We think this is simply the fairest way to do it. You should pay for the time your car is actually with us, not for dates on a calendar. While your car is with us it is watched by CCTV 24/7, and if you drive an electric car, you can add EV charging at checkout.
Look at the Total, Not Just the Rate
The daily rate is only half the story. How a car park counts its days can quietly add a full extra day to your bill, especially with late or early flights. Before you book, check your real times and look at the total. If you are flying from Dublin Airport soon, you can book your Meet and Greet parking with Dublin Valet Park and pay only for the time you actually use.
