		<h1>Local Time Google Calendar</h1>
		<h2>View Any Public Google Calendar in Your Local Time Zone</h2>

		<p>Have you ever wanted to share a Google Calendar with people in different time zones without making everyone convert the event times themselves? This page makes that easy.</p>

        <p>Simply provide the src value from any public Google Calendar embed link, and this viewer will automatically display the calendar using <strong>the visitor's own local time zone</strong>. Whether someone is in Arizona, New York, London, Tokyo, Sydney, or anywhere else in the world, Google Calendar will display the events in their local time.</p>

        <p>This tool is perfect for:</p>

        <ul>
            <li>Online events</li>
            <li>Livestream schedules</li>
            <li>Community calendars</li>
            <li>Gaming events</li>
            <li>Virtual conventions</li>
            <li>Club meetings</li>
            <li>International teams</li>
            <li>Anyone sharing events across multiple time zones</li>
        </ul>

        <p>No Google account is required to view the calendar, and visitors do not need to add the calendar to their own Google Calendar.</p>

		<h2>How to Use</h2>

		<p>Just copy and paste the <code>src</code> attribute from the embed link of your public Google Calendar after a <code>?</code> in the URL like this:</p>

		<p><code>?src=your_calendar@group.calendar.google.com</code></p>

		<p>You can also provide an entire Google Calendar embed URL:</p>

		<p><code>?src=https://calendar.google.com/calendar/embed?src=...</code></p>

		<p>So the final link would be like this:</p>

		<p><code>https://calendar.gozarproductions.com/?src=your_calendar@group.calendar.google.com</code></p>

		<p>or</p>

		<p><code>https://calendar.gozarproductions.com/?src=https://calendar.google.com/calendar/embed?src=...</code></p>

        <p>When someone opens your generated link, the calendar is automatically displayed in <strong>their own local time zone</strong>, making it easy to share schedules with people anywhere in the world.</p>
