On the first day (mùng một) and the full-moon day (rằm, the 15th) of each lunar month, many Vietnamese families light a few sticks of incense at a home altar, with fresh water, flowers and fruit. It is a folk custom rather than a fixed rulebook, and what tends to be passed down is the sincerity, not the quantity. Here is a soft retelling of the custom, plus a few ways to keep the house lighter on smoke.
Why these two days?
The lunar calendar follows the moon. The first day marks a new cycle and the fifteenth the full moon. In village life these two dates were natural markers for the market, for visiting relatives, for tidying the altar. Over time they became moments to look back on the past month and turn toward the next.
Within Vietnamese ancestor veneration, many households light incense on these days to remember grandparents and parents; others visit a pagoda. Practices vary by region, family and personal faith, so there is no single “correct” way. One stick lit with gratitude is often considered enough.
Incense on the 1st and 15th of the lunar month: keeping it simple
Many people assume these days require elaborate offerings. In many homes, a few small things are all that is done:
- Clean water or a small cup of tea, changed each time, like a morning greeting.
- Fresh flowers or seasonal fruit, modest and not fussy.
- Incense made from natural ingredients, with a gentle scent that does not overpower the home.
- A tidy altar: dust wiped, old flowers removed, ash cleared. The tidying is part of the ritual.
Some families eat vegetarian on these days, others cook a small meal and share it. All of these are personal choices. What is worth keeping is the feeling of slowing down for a few minutes, for those who came before and for yourself.
A gentle sequence
There is no required order, but if you want an easy one to remember:
- Wash your hands and open a window or door so air can move.
- Change the water, arrange the fruit and flowers, wipe the surface.
- Light the incense and stand or sit quietly for a moment: say thanks, ask permission, or simply tell them about your day.
- As the incense burns down, check the holder and the ash. Do not leave it burning with no one home.
Prayers can be long or short. Many people choose to speak silently and briefly, believing that family members hear the heart without many words.

Less smoke, same sincerity
In a small home, especially an apartment with few windows, incense smoke can sting the eyes and weigh on the air, particularly with older relatives, children or smoke-sensitive guests. A few small changes help without losing the meaning:
- Light fewer sticks: one or a few instead of a bundle. Quantity does not add to sincerity.
- Open a window while burning and for a while afterward. Place the altar where air circulates, not in a closed corner.
- Choose clear ingredients: wood powder, herbs and natural binders, without heavy synthetic fragrance. Read the label.
- Extinguish carefully: let a stick burn out in an open space, or press the tip into a ceramic dish or damp sand rather than crushing it on something flammable.
Studies of indoor incense smoke suggest it can raise fine particles in the air, so ventilation and moderation are the careful approach. If someone at home has a respiratory condition, ask a doctor and consider burning less often.

Your own household rhythm
For people living far from home, renting a room or sharing an apartment, the altar may be one small shelf. That does not make the custom any less real. A steady ceramic holder, a few gentle sticks and a cup of clear water are enough to begin a month well.
If you are curious, you can browse natural incense by scent group (Woody, Herbal, Agarwood, Soft & sweet) in the Yūgen shop, or take the scent finder to find a scent that suits your space. And even before you choose anything, keeping the slow rhythm of these two days is already a way of caring for yourself.
A few safety notes
Whether you light incense to remember someone or to settle your mind, safety comes first. Use a heat-proof holder away from curtains, paper and dried flowers. Never leave it burning when you go out or sleep. Keep incense and lighters out of children’s reach and take extra care around pets. They are small habits, but they are what keep the custom peaceful over the years.
