            return {
                options3: {
                    disabledDate (date) {
                        return date && date.valueOf() < Date.now() - 86400000;
                    }
                },
                options4: {
                    disabledDate (date) {
                        const disabledDay = date.getDate();
                        return disabledDay === 15;
                    }
                }
            }
        }
    }

var Component = Vue.extend(Main)
new Component().$mount('#app')
