I have a problem with the hotel reservation email markup system described in this page
I've included the metadata in an hotel reservation email but it doesn't detect the checkin and checkout dates correctly.
This is the metadata I used.
<div itemscope itemtype="http://schema.org/LodgingReservation">
<meta itemprop="reservationNumber" content="111111">
<link itemprop="reservationStatus" href="http://schema.org/ReservationPending">
<div itemprop="underName" itemscope itemtype="http://schema.org/Person"><meta itemprop="name" content="Guillem Test"></div>
<div itemprop="reservationFor" itemscope itemtype="http://schema.org/LodgingBusiness">
<meta itemprop="name" content="Apartamentos La Solana">
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<meta itemprop="streetAddress" content="-">
<meta itemprop="addressLocality" content="-">
<meta itemprop="addressRegion" content="-">
<meta itemprop="addressCountry" content="-">
<meta itemprop="postalCode" content="-">
</div>
<meta itemprop="telephone" content="-">
</div>
<meta itemprop="checkinDate" content="2021-01-26T16:00:00+00:00">
<meta itemprop="checkoutDate" content="2021-01-27T11:00:00+00:00">
<meta itemprop="bookingTime" content="2020-09-17T00:00:00+00:00">
As you can see, it indicates that check-in and check-out dates are 2021-01-26 and 2021-01-27 respectively, but in gmail, the check-out date detected is 2020-01-28. It always adds one day to the check-out date as you can see in this picture.
It happens with every reservation email I send.
I also tried replacing checkinDate and checkoutDate by checkinTime and checkoutTime as it says here but still doesn't work.
Hope you can help me.
Thank you!
