Launch date calculator
Pick a month. Each date is checked against the founder's driver and conductor, the weekday's planet, the personal year and month, and the name if you give one. Blocked dates are struck out, never scored low.
A launch on a date the driver reads as opposed does not fail on the day; it drags for a quarter. Founders remember the launch as unlucky when the date was simply readable in advance.

How this calculator works
- R-BLOCK Hard blocks: date number opposed to the driver; opposed to the conductor; date number 4 with a full-date digit of 4; strict mode adds 2, 4 and 8.
- R-DATE Date number: 1, 5, 6 score 90; 3, 9 score 75; 7 scores 60; 2, 4, 8 score 35; +10 as a friend of the driver; -15 for a 3 founder on a 6 date; cap 100.
- R-WEEKDAY Weekday planet friend of the driver 80, neutral 60, opposed 30; +20 when the weekday number equals the date number.
- R-YEAR Personal year 1, 5, 6 score 100; 8 scores 80; 3 scores 75; 2 scores 60; 9 scores 45; 7 scores 40; 4 scores 20; -20 if opposed to the driver.
- R-MONTH Personal month friend 85, neutral 67, opposed 40.
- R-NAME Name resonance 100 if the date number or the year digit equals the name digit; 70 if both sit in 1, 3, 5, 6; else 40. Media and digital marketing add 20 for a full-date digit of 3, 6 or 9.
Not what this tells you. A top date is the strongest date for this founder in this month, not a guarantee about the launch. Contracts, staff and stock still decide the rest.
The reason
Every calendar date carries a number, the day reduced, and every weekday carries a planet (Sunday 1, Monday 2, Tuesday 9, Wednesday 5, Thursday 3, Friday 6, Saturday 8). The date number is read against the founder, the personal year rates the year, and the personal month rates the month. Weights 28, 16, 22, 8 and 14 with a sixth of 6 for founders who are 7 or 8.
Where the schools disagree
- The source published its weights but not its sub-score rubric; the rubric above is this site's explicit definition, documented so the ranking is reproducible.
- Muhurta practice adds tithi and nakshatra. The report's Blueprint tier overlays them; this calculator reads the number layer only.

The Business Name Report scores three respellings, reads the founder in both directions, flags karmic numbers and dates a 30-day plan. The Blueprint adds the Lo Shu grid, the twelve-month calendar, partners, phone, domain and premises.
Questions founders ask
Why are some dates struck out?
Because practitioners block them outright: a date number the driver or conductor reads as opposed, or a 4 date on a 4 full-date total. Blocks are blocks, not low scores.
What is strict mode?
It also strikes every 2, 4 and 8 date, following the practitioners who avoid those numbers for any launch.
Does the business name change the ranking?
Slightly. Name resonance carries 14 of the 88 weight units and rewards a date number that matches the name digit.
Which years can I check?
From last year to six years ahead, matching the timing outlook.
