Booking.com Blocked Dates
Booking.com Blocked Dates Not Syncing
If Booking.com availability is out of sync, the key question is not whether the file downloads. It is whether the imported nights match what Booking.com actually exported.
What this page helps you fix
This guide focuses on blocked-date mismatches and overbooking exposure caused by Booking.com export timing or downstream interpretation.
Use it when bookings exist but nights are missing, shifted, or inconsistent across channels.
Symptoms of a blocked-date mismatch
Booking.com shows the stay but other systems do not block the same nights.
Availability remains open long enough to risk a double booking.
Support teams see mismatched nights after a successful import.
Why blocked dates drift
Export timing, partial imports, or date-window interpretation can all produce wrong downstream availability.
Teams often check the raw feed but skip validating the final blocked-night behavior on the timeline.
Blocked-date workflow for Booking.com
-
Step 1
Import the live Booking.com feed
Use the same export URL the PMS or channel manager reads.
-
Step 2
Force a sync and check event coverage
Confirm imported counts and review any missing or partial results.
-
Step 3
Compare blocked nights on the timeline
Check whether the imported stay blocks the same nights you expect from Booking.com.
-
Step 4
Prove source versus consumer
Use the imported evidence to decide whether the source export or downstream logic needs attention.
Blocked-date mismatch patterns
| Pattern | Likely cause | Action |
|---|---|---|
| Nights missing after import | Partial import or source timing | Inspect event counts and retry sync |
| Wrong night range blocked | Boundary handling | Compare imported window to Booking.com expectation |
| Mismatch only in PMS | Downstream mapping issue | Use iCal Tester result as the source-of-truth check |
Blocked-date checklist
- Validate imported counts and blocked nights together.
- Compare Booking.com against another source on the timeline.
- Repeat after each sync-related change.
- Keep the evidence for support and engineering handoff.

Import the live Booking.com feed and validate exactly which nights it blocks before you change downstream logic.
Inspect My Booking.com Blocked DatesFAQ
What if Booking.com blocked dates are missing?
Import the feed into iCal Tester first. If the nights are missing there too, the issue is likely in the export or its timing.
Why can blocked dates differ after a successful sync?
A successful fetch does not guarantee correct date interpretation or full event coverage.
How do I prove whether my PMS is the issue?
If Booking.com blocks the expected nights in iCal Tester but your PMS still differs, inspect your downstream mapping and persistence logic.
