This program sets the dates/date ranges / particular days of the week that surcharges apply.
Usually, surcharges do apply during peak season as well as weekends.
This is a feature in addition to the occupancy formula to manipulate the rate at a certain day, regardless of the occupancy level.
The program has 2 options. Either a surcharge is a “holiday surcharge” and requires date from & date until only. The user can choose if these holidays are annual although the days will be different. E.G. Christmas is always December 25 but the day is different.
If holiday is yes and annual "yes" it is not possible to select an of the days. If the tick box “select days” has been selected, and the user selects Holiday no and annual "no" If days have been selected and the user changes holiday = ‘y’, all
selected days will be cleared including the tick box.
