Next month Missing

Hi @mylocaltrades,
Can you please provide a screenshot of your webform booking settings so I can try to replicate it?

The is the YAML:

name:
  '#type': textfield
  '#title': Name
  '#required': true
email:
  '#type': email
  '#title': Email
  '#required': true
book_a_date:
  '#type': booking
  '#title': 'Book a date'
  '#required': true
  '#days_advance': ''
  '#excluded_weekdays':
    Mon: Mon
    Tue: Tue
    Thu: Thu
    Fri: Fri
    Sat: Sat
    Sun: Sun
    Wed: 0
  '#time_interval': |-
    09:30|10:30
    11:00|12:00
  '#slot_duration': '60'
  '#seats_slot': 12

The problem seems to be related to how javascript processes dates which was also mentioned in another issue.
I just sent a commit to fix it. Install the dev version and let me know if it solves it for you too.
composer require 'drupal/webform_booking:1.0.x-dev@dev'

Works perfectly! Thank you so much

Released as part of 1.0.13
