The month of flowers, bright days and short nights in 2025 brings us many reasons to keep an eye on the sky. The Full Moon in May, with its evocative name of Flower Moonwill arrive shortly before the middle of the month, but before that we will have two meteor showers and several conjunctions that can be seen with the naked eye.
The intense nocturnal activity to which the month of May invites us is also reflected in the numerous opportunities that the lunar calendar offers to cut your hair or shave taking advantage of the lunar influence.
In the countryside, farmers have been observing the sky for centuries to dedicate the most advisable care to plants at each moment of the lunar cycle. In biodynamic agriculture, very focused on caring for the earth in an ecological way and following cosmic rhythms, The lunar calendar is a basic tool when it comes to organizing. Their observations, collected in our 2025 lunar calendar, also allow us to calculate when the most favorable moments occur to obtain a good result if a haircut or waxing is scheduled.
We will give you more details about all of this below. You will discover when there is a full moon in May and how the phases of the moon evolve during the rest of the month, what other notable astronomical events you can write down in your diary, what times are best to plant or transplant and what are the best days to get a haircut or wax.
Moon Phases for May in 2025
The month of May is starting strong this year for those who enjoy the Moon and contemplating the planets and stars. With the Moon illuminated by 21% and growing night by night, the same day 1 gives us the possibility of seeing Mars passing through the star cluster known as The Hive and getting a little closer to our satellite every day.
On Tuesday, May 6 the Moon and Mars will meet with the constellation of Cancer, The Crab, as a backdrop.
Crescent with Mars near the Moon
The crescent phase in this month of May arrives on sunday 4so the Moon will already have Mars quite close. It will be 50% illuminated, appearing as a perfect «D» in the northern hemisphere and as a «C» in the southern hemisphere.
The night before, from Saturday the 3rd to Sunday the 4thboth will also be close to the Manger cluster. This cluster, made up of nearly a thousand stars, is one of the most popular deep sky objects and perfect for those new to stargazing. You can see it again next to the Moon on Saturday, May 31.
Full moon
During the entire first full week of May we will see how the Moon develops its hump, to one side or the other depending on the hemisphere in which you are. He monday 12coinciding with sunset, the Sun, the Earth and the Moon will align, with the Earth in the middle, and the Moon will appear to us completely illuminated.
This full moon in May, the flower mooncoincides in 2025 with the lunar apogeethe moment in the lunar orbit when our satellite is furthest from us, so it may seem a little smaller than usual. This is what experts call a micromoonalthough the difference is minimal and you will surely enjoy its magic just as much.
last quarter
As the Moon wanes and loses illumination, It will in turn get closer to the Earth and slightly increase in size.. The last quarter phase will arrive on Tuesday May 20with the Moon again illuminated at 50% but showing us the opposite half to the one it showed us during the first quarter.
The last quarter marks the countdown to the new moon. The Moon will appear increasingly thinner and more elusive, since it will no longer appear in the sky until late in the morning and, by the time the sun sets and it becomes night, the Moon will also have hidden. The best thing to see is get up early or look for it in the sky during the day.
A very close new moon
The new moon phase that closes this May lunar cycle occurs on Tuesday the 27th in the morning. That night and the previous one, darkness will reign at night, which will offer a magnificent opportunity to gaze at the stars.
This new moon will be at its perigeethe moment of closest proximity to the Earth; You will not see it but it will be there influencing the tides and making them more intense that day.
In this summary you can check at exactly what time each of the lunar phases of May occurs in 2025:
- Crescent: Sunday, May 4 at 3:53 p.m.
- Full moon: Monday, May 12 at 6:58 p.m.
- Last quarter: Tuesday, May 20 at 2:00 p.m.
- New moon: Tuesday, May 27 at 5:05
May meteor showers and other astronomical events
At the beginning of May we can enjoy a meteor shower that looks especially good in the southern hemisphere, although it can also be seen in some parts of the northern hemisphere. It is about the lrain of the Eta Aquaridswhose peak will take place between Sunday, May 5 and Monday, May 6.
The Moon will already be in the waxing gibbous phase, but in the southern hemisphere it will be setting early in the morning, leaving almost all of the early morning of Monday the 6th, until dawnthe completely dark sky in ideal observing conditions. Look toward the constellation Aquarius: that’s where the meteors will appear to originate from.
On Saturday, May 10, another less well-known meteor shower will occur due to its less intensity. It can be seen low on the horizon in the northern hemisphere, although the proximity of the full Moon, with the Moon very present and illuminated at night, will make its observation difficult.
In addition to these meteor showers, some observations stand out in the month of May apart from the conjunctions mentioned above:
- May 2: This is one of the few opportunities to see an asteroid from Earth with the naked eye. It is about Vestawhich will be in opposition to the Sun and can be seen shining in the night sky in the constellation of Libra. Using a stargazing app can help you locate it.
- May 6: occurs Saturn equinox which takes place approximately every 15 years and during which its rings remain hidden from our eyes.
- May 22: The Moon will be near Saturn and Neptunealthough without professional equipment you will only be able to see Saturn.
- May 23: you can easily identify Venus looking for it near the waning Moon, already very thin.
Lunar conjunctions offer a good opportunity to learn to identify the planets in the night sky and get an idea of the movement of the stars that populate our celestial vault.
May lunar calendar for haircuts and waxing

In the same way that the Moon influences the tides, it is considered that it can also influence other vital processes. Some studies have proven that this is the case in the case of some living beings, which adapt their growth or certain behaviors to the time of the lunar cycle. He The use of the lunar calendar in agriculture is perhaps the best-known practical application. of the wisdom accumulated by observing the lunar phases and their effect on plants and crops.
In our lunar calendar, Based on the lunar calendar of biodynamic agriculture, the most appropriate times to carry out certain tasks in the field also help us determine the best times of each month to get a haircut or wax. According to experts in biodynamic agriculture, in the same way that the Moon can influence how sap moves through plants, it can also have a subtle effect on body fluids involved in hair growth.
Based on their criteria, here we detail which are the best days in May to cut your hair if you want to strengthen it or want to stimulate rapid growth. Also which days in May are the most suitable for shaving and thus take advantage of the opposite effect: the weakening and slowing of hair growth. We do it based on the calculations made by the experts who prepare the Biodynamic farming lunar calendar by Maria Thun, published by the Rudolf Steiner publishing house.

The best times to get a haircut in May 2025 if you want to strengthen it are just before the full moonwith the Moon in the crescent phase showing its hump. This is because on these days several root periods occur according to biodynamic agriculture, and the Moon is also in descending orbit.
In the root daysthe Moon is at the height of one of the root constellations: Taurus, Virgo or Capricorn. In May 2025 they coincide with the Moon in descending orbit These days, which are ideal for cutting my hair and strengthening it. Some hours are eliminated when, due to other factors according to experts, the moment is not so favorable:
- All Friday the 9th: It is ideal for cutting your hair, as this cut will help your hair grow healthier and stronger.
- Saturday the 10th: until 5 p.m. You have another great day to cut your hair in order to strengthen it.
- Sunday the 11th: from 7 a.m. to 5 p.m. You once again have great hours to schedule a haircut.
In the orchard and garden:
In the garden, root days are considered ideal for sow, stimulate or harvest the plants that we grow for their roots or tubers; also to stimulate the roots of plants in general, removing the soil.
Apart from these days mentioned for their favorable effect when cutting hair, leaf days in May 2025 are the sunday 18 of May, the Monday 19he Tuesday 20th until 8amhe Saturday 24th from 12pm to 9pmhe Tuesday 27 of May and Wednesday 28th until 7pm.
When transplanting or pruning root plants, we must also look at the orbit:
- Until May 15the orbit will be descending, which favors the transplants and the planting cuttings. From that date until May 28, the ascending orbit opens a more favorable period for pruning and grafting.
- Since the plant sap is at the top of the plants, they will heal faster and suffer less. If you have to prune in the first half of the monthexperts in biodynamic agriculture recommend carrying out only light pruning.

To revitalize hair giving a boost to its growththe expert advice is to cut your hair in a day or period sheetmarked in green on the lunar calendar.
