I discovered this problem last night on 7.2.6 and is still there after upgrading to 7.3.0. Obviously it used to work and can still, as I have dates saved that are pre 1900 from using older versions, but can no longer enter a date before 1900. Is there any quick hack or something that I can do to fix this?

Thanks a lot for any help anybody could offer?

My bodge for now is to store dates +2000 years.

eg:

The date 01-01-760 is entered in the interface as 01-01-2760

I then subtract 2000 on output.

Dirty, but it works for now!

Thanks. That won't work for me as already have hundreds of dates in the correct format!

There must be some 'fix' for it .. I'll have to look into it further.

The date settings applied within Bootstrap Date/time picker widget: https://github.com/Eonasdan/bootstrap-datetimepicker

It's located in ./Umbraco/lib/datetimepicker directory.

All you need is to change values of minDate and maxDate properties of $.fn.datetimepicker.defaults object in bootstrap-datetimepicker.js file.

For instance I need range of dates 1800 - (now + 100 year). Then the $.fn.datetimepicker.defaults object should looks like the following:

$.fn.datetimepicker.defaults = {
    format: false,
    pickDate: true,
    pickTime: true,
    useMinutes: true,
    useSeconds: false,
    useCurrent: true,
    calendarWeeks: false,
    minuteStepping: 1,
    minDate: moment({y: 1800}),
    maxDate: moment().add(100, 'y'),
    showToday: true,
    collapse: true,
    language: moment.locale(),
    defaultDate: '',
    disabledDates: false,
    enabledDates: false,
    icons: {},
    useStrict: false,
    direction: 'auto',
    sideBySide: false,
    daysOfWeekDisabled: [],
    widgetParent: false
};

The only problem will occur after the Umbraco update, so better solution is to create Back Office "extension", "plugin", ... I don't know how it's called exactly.

The code should looks like the following:

$.fn.datetimepicker.defaults.minDate = moment({y: 1800});
$.fn.datetimepicker.defaults.maxDate = moment().add(100, 'y');

A clean and easy way to implement Aghasi's suggestion is to create a new property editor that inherits from the standard datepicker. Just add a new class to your project, and put code like this in it:

using Umbraco.Core.PropertyEditors;
using Umbraco.Web.PropertyEditors;

namespace SedgwickCountyOrg.App_Plugins.HistoricalDatePicker.PropertyEditors
{
    [PropertyEditor("HistoricalDate", "Historical Date", PropertyEditorValueTypes.Date, "datepicker", Icon = "icon-calendar")]
    public sealed class HistoricalDatePropertyEditor : DatePropertyEditor
    {
        public HistoricalDatePropertyEditor() => DefaultPreValues.Add("minDate", "moment({y: 1800})");
    }
}

Then you can add a new data type based on the HistoricalDate property editor, and use it in your document types.
