    The default calendar event popup shows (UTC-08:00) Pacific Time (US & Canada) after the time. Is there any way to alter that timezone description so it only says (PST)?

    Hi Adam,

    Please note that we get the information which we display after the event time from the system by using the id of the time zone. For example:

    var timeZone = TimeZoneInfo.FindSystemTimeZoneById("FLE Standard Time");

    The above will return for example the following:

    "(UTC+02:00) Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius"

    What I can suggest is that you use javascript in order to manage the value returned by the TimeZoneInfo system class.

    Here ia a sample javascript which you can use and further modify to fit your exact scenario:

    $(document).ready(function () {
        var utcPatern = /\(UTC.*?\)\s/;
        var calendar = $find("C001_eventsFrontendCalendar_ctl00_ctl00_viewEventDialog");
        var baseRebind = calendar._rebind;
        calendar._baseRebind = baseRebind;
        calendar._rebind = newRebind;
        function newRebind () {
            if (this._appointment.get_attributes().getAttribute("AllDay") != "True") {
                var userTimeZone = GetUserPreferences().get_timeZoneDisplayName();
                //Replace the UTC part of the time zone
                var userTimeZoneModified = userTimeZone.replace(utcPatern, "(PST) ");

    You can modify the utcPatern and use your own regular expression.

    In order to apply this javascript, please open the page where you display the Events and drop the Javascript widget where you can place the javascript code above. Under Where to include in HTML?, select Where the widget is dropped.

    In addition to this, here is also how you can get the time zone id and the time zone display name using javascript:

    // e.g. "FLE Standard Time"
    var timezoneId = GetUserPreferences().get_timeZoneId();
    // e.g. "(UTC+02:00) Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius"
    var zone displayName = GetUserPreferences().get_timeZoneDisplayName();
