Features

Timezone Timer (Multi-Timezone Publish Time Calculator) is a free browser-based tool for cross-border creators and brand social teams that converts a single ideal posting time slot into the exact wall-clock hour for 12+ common global timezones and major cities — including DST/夏令时 auto-correction. Pick a home timezone, choose your best-performing audience active hour, and the timer will show you when to press 'post' for followers in Los Angeles, New York, London, Paris, Berlin, Dubai, Mumbai, Singapore, Tokyo, Seoul, Beijing, Sydney, and São Paulo — with no API calls and no signup.

When You Need This

Common pain points this tool solves

1. Planning a TikTok/Reels global release drop time so a product launch video goes live at the same audience-peak hour across the US, EU, and Southeast Asia followers
2. Working out a weekly cross-border WeChat Moments / Xiaohongshu livestream schedule where a Shanghai-based team posts at a local-friendly time for followers in London, Dubai, and Toronto without waking up in the middle of the night
3. Aligning a multi-region brand's weekly newsletter or Twitter/X thread release so every region's subscribers receive it during their own prime work-break or commute window instead of in the middle of the night

How to Use

Step-by-step instructions

1. Choose your home or reference timezone and the target local date and hour you want to publish for your own team
2. Select the audience zones you want to calculate — 12 major cities and common global zones are preselected by default (you can toggle)
3. Hover any city row to see the offset vs. your home timezone and whether daylight saving time is active on that target date
4. Copy the per-city results as a table or list, then paste the schedule into your Notion, calendar, or scheduling tool. The tool auto-accounts for DST changes on the specific date you pick.

3. Runs 100% in-browser: no API keys, no signup, no analytics, no scheduling platform lock-in — works alongside Buffer, Later, or native platform schedulers as a pure planning reference
