Le Labo Graphic design Neither paper to tear nor screens to consult: the CALENDA magnetic perpetual calendar reinvents the way we track the days with a simple and satisfying gesture. A large black ring features the twelve months engraved from JAN to DEC; a red slide bar graduated from 1 to 31 traverses it from end to end. Magnetic black beads are moved by hand to indicate the month and the day: each morning, you slide the bead one notch, and the date is displayed in a refined visual language. A red bead placed under the ring serves as a stand, allowing it to stand upright on a piece of furniture, while a thin rod topped with a bead completes the composition. CALENDA can also be hung on the wall, where it becomes a true graphic piece. With a total width of approximately 28.3 cm, it stands out on a desk, shelf, or hallway wall without ever cluttering. A design object that is both functional and decorative, transforming a daily ritual into a small moment of tactile pleasure.
Available finish
CALENDA is offered in a unique finish with a bold contrast: the black of the ring makes the month engravings stand out, while the red of the slide bar draws the eye to the line of days. A graphic duo that suits both industrial interiors and contemporary offices.
The perpetual calendar: an ancient principle, a modern interpretation
A perpetual calendar is a calendar that can be reused year after year without ever needing to be replaced. Early models, in the form of tables, dials, or numbered cubes, already allowed for the reconstruction of any date using a small number of elements. CALENDA adopts this idea, stripping it down to the essentials: twelve months on a circle, thirty-one days on a line.
The system relies on magnetism: small magnetic beads adhere to the markings and can be moved without tools. The circle evokes the cycle of seasons that returns each year, while the straight line evokes the passage of days within the month. This dual geometry—circle and straight line—makes CALENDA an object that exists halfway between a time-measuring instrument and a wall sculpture. The day of the week is not included: it is a monthly and date calendar, intentionally minimalist.
Why you will love it
Time as a line and a circle
We think we know the calendar by heart, yet CALENDA offers a fresh take. The black circle recalls the year that turns, returns, and starts over; the red line that traverses it represents the days moving forward, one after the other, without turning back. In between, the magnetic beads mark the exact point where you are.
Hung in an entryway, it becomes a visual reference for the whole house; placed on a desk, it accompanies your workdays. What strikes you is the simplicity of the gesture: no apps, no notifications, just a bead that you move with your fingertips. An object that restores a concrete, almost ceremonial dimension to the passage of time.

Good to know: CALENDA indicates the month and date, but not the day of the week. This is a choice made for readability: the composition remains uncluttered and can be read instantly. Like any perpetual calendar, it simply requires adjusting the day bead at the end of the month, especially after months with 28, 29, or 30 days.
Tip: for the wall-mounted version, install CALENDA in a high-traffic area—entryway, hallway, kitchen, or office—and associate moving the bead with a morning ritual, like making coffee. The gesture quickly becomes automatic, and the calendar stays up to date.

Frequently Asked Questions
How does this magnetic perpetual calendar work?
CALENDA is based on two scales: a black ring bearing the twelve months engraved from JAN to DEC, and a red slide bar graduated from 1 to 31 that crosses the ring. Magnetic beads adhere to the markings and can be moved by hand. To display the date, simply place one bead opposite the current month on the ring and another opposite the day on the slide bar. Each morning, move the day bead one notch; at the end of the month, return it to 1 and move the month bead. The calendar can thus be reused indefinitely, year after year, without batteries or paper.
Can it be hung on the wall?
Yes. The photos show CALENDA both placed on furniture and mounted on the wall. When placed on a surface, it stands upright thanks to the red bead located under the ring, which acts as a stand: a shelf, desk, or console table are perfect. On the wall, it becomes a true graphic piece, preferably installed at eye level in a high-traffic area. The exact wall-mounting system (hook, nail, screw) is not detailed by our supplier: please ensure you use a mount suitable for your wall and verify that it is secure before leaving it in place. In both configurations, the beads remain easy to move with your fingertips.
Does the calendar indicate the day of the week?
No. CALENDA indicates the month and date (from 1 to 31), but not the day of the week. This choice of simplicity preserves the readability and elegance of the composition: a circle, a line, and a few beads are enough to locate the day within the year. For those who like to have all information at a glance, CALENDA pairs very well with a clock or a diary. It is intended primarily for those seeking a functional design object that marks the passage of time visually rather than exhaustively. Its minimalism is precisely what makes it a decorative object in its own right.
What are the calendar dimensions?
Based on the dimensions visible in the manufacturer's photos, the total width of CALENDA is approximately 28.3 cm (11.14 inches), including the slide bar. This size provides a good sense of its presence: large enough to be read from a distance on a wall, yet compact enough to find a place on a desk or shelf. The exact height, depth, and weight have not been provided: we prefer not to estimate them. If space constraints are a concern, please do not hesitate to contact us before ordering, and we will provide you with all available information.
Is there a risk of the beads falling off?
The beads are magnetic and adhere to the markings on the ring and slide bar, allowing them to stay in place daily, whether the calendar is standing or wall-mounted. However, they remain removable by design, since they are moved by hand: an impact, dropping the object, or rough handling could dislodge them. We recommend installing CALENDA on a stable surface or fixing it securely to the wall, away from areas where it might be bumped. Please also keep the beads out of reach of young children and animals due to the risk of ingestion related to the small magnets.
Are batteries or a power source required?
No, CALENDA works entirely manually. It contains no batteries, electronic mechanisms, or motors: your actions update it by moving the magnetic beads. This is one of its great strengths: no recharging, no battery replacements, no malfunctions to worry about, and perfectly silent operation. This functionality makes it a sustainable object that you can keep for years without special maintenance, other than occasional dusting with a soft, dry cloth. It thus naturally finds its place in a bedroom, living room, or office, without visible cords or nearby outlets.
Is this calendar suitable for a child?
CALENDA is primarily a decorative object intended for adults. It contains small, removable magnetic beads that present a risk of ingestion: it is not suitable for children under 3 years old and must be kept out of their reach. The ingestion of multiple magnets can cause serious internal injury. For older children, it can serve as a fun tool to learn months and dates, provided it is installed out of reach and used under adult supervision. As a precaution, also keep it away from anyone with a cardiac pacemaker and sensitive magnetic media.
