Lunar day 15

The lunar day turns at moonrise, not midnight, so day 15 rarely lines up with a calendar date — most dates hold two different readings. Everything below is traditional material, quoted as it was received.

Favoured on lunar day 15

Colour my hair: The tradition explicitly recommends dyeing the hair on this day as part of caring for it.
Clear things out: On the 15th lunar day the tradition recommends decluttering as a way to refresh the home's energy.
Fix or repair something: Handling repairs is named outright as a good use of the 15th lunar day, especially when working alone.
Pay attention to dreams: The tradition holds that today's dreams reveal hidden traits and their personal symbols deserve attention.
Deep clean: Cleaning and other home chores done alone are considered the best use of this day.
Make something: The tradition favours finishing and polishing existing work today rather than launching something new.
Move or renovate: The tradition points to handling household repairs alone on this day as productive and balancing.
Cook or host a meal: The tradition stresses freshly prepared, high-quality food on this day.
Exercise or train: The tradition points to gentle, solo practice today rather than strenuous training.
Look for work: The tradition makes the outcome depend on the groundwork already laid, so a job search may go either way today.
Make a big purchase: The tradition says the outcome of business moves today depends entirely on the groundwork already laid, so a big purchase is only advised if it was well prepared.
Negotiate or ask for a raise: The tradition makes the outcome depend on your earlier preparation: act boldly if the ground is laid, otherwise wait.
Sign a contract: The tradition says the outcome depends on your earlier groundwork: sign boldly if it was well prepared, otherwise wait.
Start something new: The tradition makes the outcome depend on the person's earlier preparation: bold action if the ground was laid, postponement if not.

Discouraged on lunar day 15

Nails: This day is said to be one to avoid for manicures.
Travel: The tradition considers this day unfavourable for travel, expecting exhaustion and transport mishaps.
Cut my hair: The tradition advises avoiding haircuts on this day.
Intimacy with a partner: This day is named outright as one to hold back on physical intimacy, with provocations in the air.
Compete or push hard: This day is held to call for balance over intensity, with strenuous, competitive effort seen as depleting.
Prune or cut back: The tradition considers this a poor day for pruning.
Start learning something: The tradition advises reviewing familiar material instead of starting anything new on this day.
Study or sit an exam: Study and exams are both seen as poorly supported, with only review of familiar material advised if unavoidable.
Have a hard conversation: Tradition warns that people are provocative today, making a difficult conversation likely to escalate.
Get married: With provocations likely and gift-giving and intimacy discouraged, tradition treats this as an ill-suited day for a wedding.
Go on a date: Tradition describes this as a provocative day when intimacy is best postponed, so it discourages romantic meetings.
Apologise or make up: The tradition warns of a provocative atmosphere, so sensitive attempts at peace-making may misfire.
Time with family: The tradition warns that people are provocative today, so close company is easily strained.

How much weight to give this

This is inherited material, not a finding. When we checked these readings against the tradition's own named authorities, they contradicted each other on all 29 lunar days — the same day called auspicious by one source and ruinous by another. We publish what the corpus says and label it, rather than choosing the most confident version and calling it settled.

What is exact is the astronomy: when day 15 begins and ends where you are, down to the minute.
