Q: What factors affect the countdown accuracy?
It mainly depends on the accuracy of your device's system time. If your device time has a significant error, we recommend syncing it with network time to ensure an accurate countdown.
Please ensure your device's system time is accurate. Setting the time zone to UTC+8 will provide the most accurate results. The countdown is calculated based on the Gregorian calendar and is unrelated to the lunar calendar. If you stay on the page for a long time, it is recommended to refresh to get the latest data.
For event planners, we recommend setting reminder milestones at 30 days, 7 days, and 1 day before the countdown ends. Typical application scenario: Businesses can start event preparations at the 60-day mark, finalize the event plan at 30 days, and make final confirmations at 7 days.
