No. The timings are computed from an ephemeris and are exact; the guidance is inherited tradition, whose own authorities disagree on every lunar day. MoonIQ labels which is which.

Negotiate or ask for a raise, by the Moon

Of 29 lunar days, the tradition favours 17 for this and discourages 10. The lunar day turns at moonrise, so a calendar date usually spans two of them — which is why a date can be good for part of the day and not the rest.

Favourable lunar days for negotiate or ask for a raise

Lunar days to avoid

Lunar day 1: The tradition treats this as a day for planning rather than settling matters, so a raise request or negotiation is better thought through than raised.
Lunar day 4: The tradition holds this to be a day for paperwork rather than people, so important talks and decisions are best postponed.
Lunar day 8: The tradition advises putting off talks with your boss today, which covers raising the subject of a raise.
Lunar day 9: The tradition warns that deals and decisions made today may turn out other than they seem, so bargaining is discouraged.
Lunar day 19: The tradition advises against agreeing to proposals and against contact with people today, so bargaining is discouraged.
Lunar day 22: The tradition advises avoiding business dealings and important decisions today.
Lunar day 23: The tradition explicitly warns against taking part in negotiations on this contentious day.
Lunar day 26: The tradition warns that offers made today may be incomplete or ill-intentioned, so it is a poor day to strike terms.

Lunar day 29: The tradition calls for rest and putting off meetings and money matters, adding that even rewards given today leave people dissatisfied.

What this is, and is not

Inherited material, quoted as received. Checked against the tradition's own named authorities, these readings contradict each other on all 29 lunar days — so treat the guidance as a custom worth knowing, not a finding.
