start date and end date is not work with geojson data

This is only for timeDimension itself.
Features on geoJSON only support time or times array : https://github.com/socib/Leaflet.TimeDimension#ltimedimensionlayergeojson

You can change this behavior by overriding _getFeatureTimes or _getFeatureBetweenDates on a geoJSON layer subclass.
Change _getFeatureTimes to return an array of time based on the period parsing.
see Example 15

L.TimeDimension.Layer.GeoJsonWithPeriod = L.TimeDimension.Layer.GeoJson.extend({
    _getFeatureTimes: function(feature) {
        if (!feature.properties) {
            return [];
        }
        if (feature.properties.hasOwnProperty('times')) {
            return  L.TimeDimension.Util.parseTimesExpression(feature.properties.times);
        }
        return [];
    }
})

Something like that.
