Blue Moon Dinner: Dates and Three Recipes

A blue moon dinner can be lemon rice with cucumber and white bean salad, followed by blueberry yogurt bowls. The Royal Observatory Greenwich defines a blue moon as either the second full moon in a calendar month or the third full moon in an astronomical season containing four.

Blue moon dinner at a glance

The dates come from the Royal Observatory’s blue moon calendar. Go straight to the three recipes if you are ready to cook. Pick a dish you already want to eat and use the occasion to give dinner a little attention. The menu works tonight too, if you want to try it before the next blue moon.

What makes a full moon a blue moon?

The two definitions count full moons in different periods. To identify a monthly blue moon, check whether your local calendar month has two full moons, then identify the second. Counting seasonal blue moons means looking between an equinox and the next solstice, or a solstice and the next equinox. The Royal Observatory identifies the third full moon in a season with four as the seasonal blue moon.

NASA’s Tracy Vogel explains in Super Blue Moons: Your Questions Answered that the lunar phase cycle takes about 29.5 days. A calendar month can therefore accommodate a full moon near its start and another near its end. NASA gives monthly blue moons an interval of roughly two to three years.

That name does not predict a blue appearance. NASA explains that smoke or dust particles can sometimes make the Moon look blue by scattering red light. Blueberries in this menu are Hearthlight’s visual choice, alongside their published food correspondence below.

The next blue moon dates through 2028

These are the upcoming dates after this article’s October 2026 revision. The Royal Observatory confirms the classifications; the U.S. Naval Observatory supplies the full moon times in its annual phase tables. Each cell gives the local date and time of the full moon instant.

The USNO phase times are May 20, 2027 at 10:59 Universal Time and December 31, 2028 at 16:48 Universal Time. Conversions follow its U.S. Time Zones table. May uses daylight time in the four columns; a place observing Mountain Standard Time all year gets 3:59 a.m. MST. These are phase times. Moonrise requires a calculation for your location.

The seasonal date is easier to understand by counting. USNO’s 2027 phase and seasons tables put four full moons between the March equinox and June solstice. In the U.S. zones above, their dates are March 22, April 20, May 20 and June 18. May’s full moon is third.

For December 2028, USNO lists the first full moon at December 2, 01:40 Universal Time. That converts to the evening of December 1 in these U.S. zones, followed by the December 31 full moon. Local dates matter when counting a monthly blue moon.

Use the date to choose your dinner evening. Hearthlight suggests eating when it suits your household, even when the full moon instant falls during breakfast hours. Write the definition beside the date in your kitchen notebook.

Foods and their planetary correspondences

Scott Cunningham’s Cunningham’s Encyclopedia of Wicca in the Kitchen, consulted in its 2003 edition, gives the following food correspondences. The dish column is Hearthlight’s own pairing. These assignments describe magical purposes in his book.

A planetary correspondence belongs to the ingredient; the dinner date is our choice. You can compare more foods in magical correspondences for cooking ingredients.

Hearthlight’s magical correspondences feature keeps its own ingredient set. Its cucumber entry adds clarity and purification; blueberry adds wisdom, peace and clarity. Lemon shares purification with Cunningham but lists clarity, healing and protection alongside it. The app files rice under the Moon and earth, with prosperity, grounding, comfort and blessing. Rice in witchcraft compares the published lists in more detail.

Three dishes to make tonight

The rice method follows USA Rice’s cooking chart. Salad and sauce adapt Food Hero’s Bean Salad and Any Berry Sauce. Hearthlight chose the seasonings and serving combinations, along with the intention prompts. Wash your hands and rinse fresh produce under running water before preparing it, as Food Hero directs.

Lemon rice, four side servings. Put 1 cup (about 200 g) of long grain white rice, 2 cups (480 ml) of water, 1 tablespoon of olive oil and 1/2 teaspoon of salt in a 2-quart (2-liter) saucepan. Follow your rice packet if its water ratio or timing differs. Bring to a boil, stir once, cover tightly and reduce the heat to low. Simmer for 15 to 18 minutes, until the water is absorbed and the rice is tender. If needed, cover and cook another 2 to 4 minutes, following USA Rice’s advice.

Take the pan off the heat and leave covered for 5 minutes. Fluff with a fork, then fold in 1 teaspoon of finely grated lemon zest and 1 tablespoon of lemon juice. Allow about 30 to 35 minutes including preparation and heating. As you put the lid on, name who you are cooking for. “Enough dinner for the people here” is a possible intention.

Cucumber and white bean salad, four servings. Drain and rinse one 15-ounce (425 g) can of cooked white beans. Cut enough cucumber into 1/2-inch (1.25 cm) pieces to make 2 cups. In a bowl, whisk 2 tablespoons of olive oil with 1 tablespoon of lemon juice, 1 tablespoon of cider vinegar and 1/4 teaspoon of salt. Fold in the cucumber and beans. Preparation takes about 15 minutes; serve immediately or cover and refrigerate until dinner.

For a peace intention, think about what would make the table easier for someone eating with you. That could mean serving the dressing separately for a person who prefers a plain salad. Ask them before mixing their portion. If a warm side suits your evening better, potato symbolism and cooking uses gives dishes with a different set of purposes.

Blueberry yogurt bowls, four portions. Mix 2 tablespoons (30 ml) of cold water with 1 1/2 teaspoons of cornstarch and 2 tablespoons of sugar in a small saucepan. Add 2 cups of fresh or frozen blueberries. Heat over medium heat, stirring frequently, for about 10 to 15 minutes, until the berries soften and the sauce bubbles gently and thickens.

Transfer the sauce to a shallow bowl and refrigerate for 10 to 15 minutes, until lukewarm or cooler. Divide 2 cups of plain yogurt between four bowls and spoon the sauce over them. Allow about 35 minutes including preparation and cooling. For a serving without dairy, choose plain soy or coconut yogurt. Set aside a portion for anyone arriving later and keep it refrigerated.

To make the whole menu, start the berry sauce, then put on the rice. Mix the salad while both pans cook and cool the sauce while the rice finishes. Check the pans often enough to stir the sauce without lifting the rice lid. Serve the rice and salad first, leaving the yogurt cold until dessert.

A meal ritual and preparation notes

Hearthlight’s suggestion is to choose one purpose for the meal and attach it to something you can do. If you want more regular dinners at home, write the next two dinner dates on your calendar before you eat. A meal for sharing might end with packing a portion for someone who asked for it.

Keep the words specific. “I will cook dinner before I start work tomorrow evening” gives you an action to follow. Say it while the rice is covered, then sit down to eat. Afterwards, record whether the quantities suited your table and which dish you would repeat.

Prepare by choosing your guest count and checking what is already in the kitchen. Buy the ingredients that are missing, then decide which saucepan will hold the rice. For a solo dinner, halve the rice and salad quantities or cook the full amounts and follow the leftover guidance below.

A personal astrology practice can sit beside this meal. Hearthlight’s birth chart calculator shows your natal Moon placement. The calendar date above describes an event in the sky, while that placement comes from your birth information. You can create a Hearthlight account to use the app’s meal planning tools and ingredient correspondences.

Where the blue moon calendar tradition comes from

The Library of Congress Science Reference Section traces the seasonal scheme to the Maine Farmers’ Almanac. In that system, the third of four full moons in a season was named blue, keeping other named moons in their intended places in the year.

The same account describes James Hugh Pruett’s March 1946 article in Sky & Telescope. Pruett interpreted an almanac account as meaning the second full moon in a calendar month. That interpretation became widely used. The Library of Congress calls this modern American folklore.

Those records explain the calendar name. The menu and meal ritual on this page are Hearthlight’s modern suggestions. If you cook a family recipe for the occasion, name the person or memory that gives it meaning to you.

Food safety for this menu

The Food Standards Agency explains that bacterial spores in uncooked rice can survive cooking. Put leftovers away before spending time outside looking at the Moon. The FDA’s discard limits apply to rice too; reheating does not rescue food that has been left out too long.

Frequently Asked Questions

What should I serve for a blue moon dinner?

Try lemon rice with cucumber and white bean salad, then blueberry sauce over yogurt. The three recipes above serve four and use ordinary ingredients. Hearthlight chose this menu for the occasion.

What foods are associated with a blue moon?

Cunningham assigns cucumber, lemon and blueberry to the Moon in his kitchen encyclopedia. Rice belongs to the Sun in that book. Hearthlight combines them for this dinner; the blue moon timing and blue color theme are our choices.

What can I do on a blue moon?

Make dinner around a purpose you can name. A practical next step might be recording the next dinner you intend to cook before sitting down to eat; this is Hearthlight’s suggestion.

What blue moon traditions are documented?

The Library of Congress documents the Maine Farmers’ Almanac seasonal naming system and Pruett’s 1946 magazine interpretation behind the monthly meaning. Those are records of calendar terminology. The cooking practice on this page is Hearthlight’s own.

How can I make a blue moon ritual for manifestation?

Use the meal to name something you want to work toward, then choose a practical next step. For more regular home cooking, put two dinner dates on the calendar. This is Hearthlight’s intention exercise, with a plan you can check afterwards.
