Alarmclock template is a day off

been using this since a very longtime, aided by @petro (please have another look…), and now, all of a sudden, the count of days is a day of, when the alarm time is over 24 hours… (might even be 23 hours and 54 minutes)

Next alarm day:

        value_template: >
          {% set timestamp = states('sensor.next_alarm_timestamp')|int %}
          {% set days = states('sensor.number_of_days_next_alarm_calc') %}
          {% set day_dict = {'0': 'Today,', '1': 'Tomorrow,', '2': 'The day after tomorrow,'} %}
          {% set date = timestamp|timestamp_custom(' %A, %-d %B') %}
          {% if days == '-1' %} Not set
          {% elif days in day_dict %} {{day_dict[days] + date}}
          {% else %}{{'Next' + date}}
          {% endif %}

days to next alarm:

      number_of_days_next_alarm:
        friendly_name: Days to next alarm
        entity_id:
          - sensor.time
          - sensor.number_of_days_next_alarm_calc
          - input_boolean.alarmclock_wd_enabled
          - input_boolean.alarmclock_we_enabled
        value_template: >
          {% set days = states('sensor.number_of_days_next_alarm_calc') %}
          {{'Not set' if days == '-1' else days}}

and the number_of_days_next_alarm_calc, the above use in the templates:

        value_template: >
          {% set timestamp = states('sensor.next_alarm_timestamp')|int %}
          {% if timestamp %}
            {% set time = now().replace(second=0).replace(microsecond=0) %}
            {% set midnight = now().replace(hour=0).replace(minute=0).timestamp() + 86400 %}
            {% if timestamp > midnight %}
              {{((timestamp - time.timestamp()) // 86000)|int + 1}}
            {% else %} 0
            {% endif %}
          {% else %}
            -1
          {% endif %}

what could be wrong here, did HA 113 change anything to influence this?
