    function getCurrentDateStr() {
        var month = d.getMonth() + 1;

        return d.getFullYear() + '-' +

        var current_report = null;

        $('.program-body__td--time').each(function (index, value) {

The parameter index is not used and could be removed.

The parameter value is not used and could be removed.

            if (current_report !== null) {
                prev_report = current_report;
            }
            current_report = $(this);
            if (now_time < current_report.text()) {

There is no return statement if now_time < current_report.text() is false. Are you sure this is correct? If so, consider adding return; explicitly.

                if (prev_report !== null) {
                    scrollTo = prev_report;
                } else {
                    scrollTo = current_report;
                }
                return false;
            }
        });
        if (scrollTo !== null) {
            $('body,html').animate({
                scrollTop: scrollTo.offset().top - 125
            }, 600);
        }
    }

    var event_header_date_element = $('.event-header__date');
    if (event_header_date_element.length) {
        var d = new Date();
        var now_date = getCurrentDateStr();
        var event_date = event_header_date_element.attr('datetime');

        if ('scrollRestoration' in history) {

The variable history seems to be never declared. If this is a global, consider adding a /** global: history */ comment.

            history.scrollRestoration = event_date === now_date ? 'manual' : 'auto';
        }
        if (event_date === now_date) {
            scrollToNearReport();
        }
    }
});
