about shippy
A birthday lookup for
The Secret Language of Relationships
Shippy is an independent relationship guide based on The Secret Language of Relationships by Gary Goldschneider and Joost Elffers. Choose two birthdays to find their relationship profile, or explore the best and worst matches for one birthday.
It covers friendship, love, marriage, family, work, and other relationships. Each profile brings together its strengths, weaknesses, best and worst relationship types, and description.
How does the birthday lookup work?
Shippy maps each month and day to one of 48 personology periods. Two periods identify one of 1,176 relationship profiles. Swapping the order of the birthdays gives the same profile.
Do I need a birth year or time?
No. Choose a month and day for each person. You do not need a birth year, birth time, birthplace, or an account.
Can I look up friendship and work relationships?
Yes. The Best/Worst page groups date ranges by relationship type, including friendship, family, work, love, and marriage. Click a range to open its profile with your selected birthday.
Can I share a birthday comparison?
Yes. After you select both dates, copy the address from your browser. The link includes the two months and days so someone else can open the same comparison.
