Cat, Not Rabbit

While the Chinese zodiac uses the Rabbit, the Vietnamese zodiac proudly features the Cat (con Mèo). This distinction stretches back centuries — rooted in folklore where the Rat betrayed Cat during the Great Race across the river.

And it's not just the Cat. Vietnamese zodiac uses Water Buffalo (Trâu), not Ox — tied to the Red River Delta farming culture that shaped Vietnamese civilization. The Buffalo is a symbol of hard work, patience, and the rice paddies that feed the nation.

Mindfulness, Built In

Vietnamese zodiac is deeply intertwined with Buddhist tradition. Sao Mai tracks vegetarian observance days — from 2 days per month to 10 days per month — honoring the Bodhisattvas associated with each sacred day.

The app also marks all 20 major and minor Buddhist holidays, taboo days (Tam Nương, Nguyệt Kỵ), and auspicious hours (Giờ Hoàng Đạo). Every feature is grounded in mindfulness: even a difficult day is an opportunity for reflection, not a reason for fear.

Vegetarian Observance

2-Day Vegetarian 2 days/mo
4-Day Vegetarian 4 days/mo
6-Day Vegetarian 6 days/mo
10-Day Vegetarian 10 days/mo
