Launch Timezone Coordinator

Why coordinate timezones for a launch?

When you launch a SaaS product, your audience isn't limited to your city—it's global. If you announce on Twitter, "We are launching at 9 AM!", half your audience won't know if that's 9 AM in San Francisco, London, or Tokyo.

By explicitly listing global timezones in your launch tweet, you remove all cognitive friction. It makes it dramatically easier for supporters around the world to set calendar reminders and upvote your product at the exact moment you drop.

What time does Product Hunt reset?

The Product Hunt daily leaderboard resets exactly at 12:01 AM PST (Pacific Standard Time). WonderLaunch also operates on PST.

If you want to maximize your exposure and get a full 24 hours on the leaderboard, you must coordinate your launch to happen exactly at this time. Converting PST to your local time—and the local time of your biggest user bases—is critical for a strong Day 1 push.

How to use the Timezone Coordinator

Use this tool to generate the perfect launch-day announcement text:

1. Select your base time: Pick the exact date and time you intend to hit the "launch" button.
2. Choose target cities: Select major tech hubs (e.g., San Francisco, London, Berlin, Tokyo) where your followers live.
3. Copy the output: Click the "Copy to Clipboard" button to grab the formatted text block and paste it directly into your Twitter thread, LinkedIn post, or email newsletter.

Best practices for global announcements

• Don't list more than 5 timezones: A massive wall of text is hard to read. Stick to PST, EST, GMT, CET, and JST.
• Use emojis: Visual flags (🇺🇸, 🇬🇧, 🇯🇵) help people scan for their timezone instantly.
• Announce 24 hours prior: Post your timezone-coordinated tweet exactly 24 hours before launch to build hype.
