Tilem: The New Moon Holy Day in the Balinese Calendar

Tilem is the new moon day in the Balinese lunar calendar, marked by offerings and prayers at temples and family shrines. For a visitor, it is the phase of the month when the island feels quieter and more inward than it does at full moon. Temples still receive offerings, households still set out small trays of flowers and rice, and in many villages the day shapes what people do with their time, from ceremonies to the choice of when to start a piece of work. The sections below explain how tilem is set, what people do on it, and how to behave respectfully if your travel dates fall on one.

What tilem means in the Balinese calendar

The Balinese use two calendars that run side by side. The first is the lunar Saka calendar, which divides the year into twelve sasih months. Each sasih begins on the day after a tilem, so the new moon closes one month and opens the next. The full moon, called purnama, falls roughly in the middle of each sasih. Between the two, the month moves through a waxing phase and a waning phase, and the calendar treats the two ends of that cycle as separate moments of ritual weight.

Because the Saka year is built on the moon, it runs for about 354 or 355 days, which is shorter than the solar year. Adjustments are made so that the lunar months stay roughly in step with the seasons that matter to farmers. Some years carry an extra intercalary month. The practical result for anyone planning a trip is that tilem does not fall on a fixed date in the Gregorian month. It moves from year to year, and the only dependable way to find it is to check a Balinese calendar printed for the current year or ask a local family, a banjar member or a temple caretaker.

How tilem sits alongside the Pawukon calendar

Tilem is only one part of the picture. The second calendar, the Pawukon, is a cycle of 210 days made up of thirty seven-day weeks, and it runs independently of the moon. Many temple anniversaries, called odalan, are set by the Pawukon rather than by the lunar month. When a temple’s birthday lands on a tilem, the temple will hold its ceremony on that day, and when it does not, the odalan keeps its own schedule. This is why a visitor can see a large temple celebration in the middle of a new moon week, or find a quiet village temple full of families on a day that has nothing to do with the moon at all.

The two systems also combine when people choose days for important family events. Balinese households often consult a calendar before scheduling a house inauguration, a building project or a wedding, and a tilem day is one of several days that a family may or may not favour depending on how it lines up with the Pawukon week. A visitor who asks a local about a date will often hear both the lunar and the weekly reference in the same answer.

Offerings and prayers on a new moon day

On tilem, the most visible sign of the day is the offering. Small woven trays of flowers, rice and incense, known as canang, appear at the entrances of shops and houses, on the steps of shrines and at the corners of streets. Most of these are made by women in the household in the early part of the day, and they are placed and replaced through the morning and afternoon. The offering is the core act of devotion, and it is repeated on many other days too, so tilem is not a day when offerings suddenly appear.

At household shrines, which Balinese families call the sanggah or merajan depending on the family and the village, prayers are directed to the divine presence through the shrine. Families who keep a shrine often make a larger set of offerings on the full and new moons than on ordinary days. In some communities the temple caretaker, known as the pemangku, has a fixed set of offerings for these two points in the month, and the household follows his lead on the specifics. The pemangku is usually the person to ask if you want to know what a particular offering is for or which temple in the area keeps its own lunar observances.

Tilem is also associated with purification and letting go. Many Balinese describe the day as a time to clear the mind of old worries and to reset, and some people prefer to fast lightly, avoid arguments or spend more time in quiet reflection. This is a matter of personal practice rather than a rule that binds everyone, and families differ in how strictly they observe it. A visitor will see the effect more than the rule: a little more calm in the street, a few more people walking to the temple in the evening, and fewer loud gatherings in the villages that keep the calendar closely.

Ceremonies that fall on tilem

Some ceremonies are timed to the new moon for specific reasons. A house inauguration, known in Balinese as mlaspas, can be scheduled for a tilem day, and the family shrine is traditionally dressed in white cloth for the occasion. A lamak, which is a long palm-leaf hanging, is placed at the entrance of the shrine, and offerings are set in the triangular upper part of the lamak for the deity who guards the land. These ceremonies are private family events, so a visitor will rarely see them unless invited, but they show how the new moon shapes the building and moving of homes.

Temples dedicated to the dead, the pura dalem, hold their own observances on tilem days, and these are often busier than other temples on the same date. Visitors may find more families and more offerings at these temples, and the atmosphere is quieter than at a full moon festival. If you visit a pura dalem near a tilem, dress carefully and keep your distance from the central shrine, because the ceremony is intended for the families who are praying there.

What a visitor is likely to notice

On a tilem, most of the changes are small. A traveller walking through a village will see fresh offerings in more places than usual, and may notice people carrying trays towards the temple in the late afternoon. The day is not a public holiday, so most shops, tourist services and attractions keep their usual routine.

Large temples can draw more families on ceremony days, so arriving earlier in the day is a sensible habit if you intend to visit one on a tilem.

How to behave respectfully at a temple or shrine

Dress is the first thing to get right. Shorts, swimwear and revealing clothing are not appropriate inside a temple, and shoulders and knees should be covered. A sarong, or kain, and a sash, or selendang, are expected when you enter the inner courtyard or join a ceremony. Many visitors bring their own, but if you arrive without one, rental and sale are common near the main temples.

Several everyday habits matter too. Do not touch the offerings, even if they look like a gift left on the ground, because they are made for the divine presence and not for passers-by. Avoid pointing your feet towards an altar or a priest, and do not step over an offering. Walk around people who are praying rather than in front of them, and keep your voice low. Ask before you take photographs of a ceremony, and use a longer lens rather than moving close into a family’s prayer. Donations are customary at many temples, and a small contribution in the donation box is a normal way to show respect.

Menstruating women are traditionally asked not to enter temples, a rule that many Balinese families still follow. If you are unsure whether a particular temple applies this rule, ask a member of the community before entering.

How tilem compares with purnama

Tilem and purnama are the two anchors of the Balinese lunar month, and visitors often confuse them. Purnama, the full moon, is the more festive phase. Temples are busier, ceremonies are larger, and some of the big temple anniversaries are held on a full moon, so you will see more dancing, puppet performances and processions at full moon than at new moon. Tilem is quieter, more reflective and more focused on the family and the household shrine. The difference is one of tone rather than of importance, and both phases carry their own offerings and prayers.

If you can only plan one lunar observance into your trip, a full moon is usually the more rewarding for seeing public ceremonies. A new moon is more useful if you want to understand how daily life and household ritual fit together, and if you prefer a calmer atmosphere to watch from the edges. You can read more about the wider calendar on the full moon page, which sets out the same cycle from the other side.

Where tilem fits in the wider calendar

Tilem belongs to the wider calendars and offerings section of this site, which covers how the lunar, weekly and ritual systems interlock. The lunar calendar is one of several frameworks that shape Balinese life, and it works alongside the Saka year and the Pawukon weeks. If you want the full structure, start with the sasih lunar calendar, which explains how the twelve months are named and how the new and full moons mark their edges. The Pawukon calendar covers the 210-day cycle that decides most temple anniversaries, and the two together explain why a single date can carry several meanings at once.

The offerings that appear on tilem are part of a wider system of ritual items. The banten offerings page explains the larger ceremonial trays that are prepared for major occasions, while the holy water page covers the water used in many of the same rites. A visitor who sees holy water being sprinkled at a shrine on a new moon will find that page a useful next step.

Planning a visit around a new moon

For most travellers, the simplest plan is to ask two questions before choosing dates. First, which temple are you hoping to see, and does it hold its own anniversary near the date you are considering? Second, do you want public ceremony or a quieter view of daily practice? A temple that is known for large ceremonies is best approached on a full moon or on its own odalan, while a neighbourhood temple or a village shrine is usually more relaxed on a new moon.

Check the calendar before you travel, and check again on arrival, because local ceremonies can shift for reasons the household knows and a visitor may not. A local guide, a hotel staff member or a shopkeeper near the temple will often tell you the date of the next ceremony, and asking is a normal part of learning about the island. If you go with a guide, let them choose the route, and follow their lead on where to stand and when to take photographs.

Common questions about tilem

Is tilem a public holiday in Bali?

No. Tilem is a day in the lunar calendar rather than a national holiday, so ordinary services and most attractions normally continue. Some households and villages observe the day more closely than others.

Can tourists join a tilem ceremony?

Many temples welcome visitors to watch from the edges, provided they dress correctly and keep their distance. Family ceremonies at home are private, and it is best to wait for an invitation rather than to ask to attend.

Why do the dates change every year?

Because the Saka calendar is built on the moon, and the lunar year is shorter than the solar year, the dates of tilem move across the Gregorian calendar. A printed Balinese calendar for the current year gives the exact date.

Do I need to bring an offering?

Visitors are not expected to bring one, and you should not take or move offerings that others have placed. A small donation at a temple is a normal way to take part respectfully.
