Sắp Tết: Tết countdown and Vietnamese lunar calendar in every new tab

Hi Product Hunt! 👋 Tết, the Vietnamese Lunar New Year, is the biggest holiday of the year in Vietnam, and "how many days until Tết?" is a question people ask all the time. So we built Sắp Tết ("Tết is coming"). - Every new tab shows a live countdown to Tết 2027 (Saturday, 6 February) in Vietnam time. - It also shows today's date on the Vietnamese lunar calendar, with the can-chi day and month. - Upcoming holidays (Vietnamese Women's Day, Teachers' Day, New Year…) appear with days left. - The toolbar badge shows how many days are left. It's free, has no account and no ads, and only asks for the "alarms" and "search" permissions. The interface is in Vietnamese, because it's made for Vietnamese people at home and abroad. We also run sapdentet.vn, a Vietnamese guide to Tết: dates, customs, recipes and greetings. Feedback very welcome!
