Presidents and Prime Ministers

Every U.S. president and every leader of the other G7 governments: about 250 people across three centuries.

The question: Do the people who reach the top of government share numbers, signs or birthdays?

What stands out

No clear differences. Across every group of 50 or more and every measure, the numbers are within what chance produces.

Worth watching, not enough to claim

  • Birth quarter

    Japanese PMs: Jan–Mar appears 28 times against about 16.3 expected (1.72×).

  • Birth quarter

    All G7 leaders: Jan–Mar appears 82 times against about 63.3 expected (1.30×).

  • Day energy

    All G7 leaders: 11 day energy appears 37 times against about 24.7 expected (1.50×).

Since 1945: every birth quarter is within normal variation of random birthdays from the same years.

Context What explains it

The 45 U.S. presidents alone are too few to show a real pattern: with that many people, a birthday or sign can easily appear several times by chance. Together with the leaders of the UK, Canada, France, Germany, Italy and Japan they make a group large enough to test.

Many of these leaders were born before modern birth registration. Only dates that the sources agree on to the day are used.

Source The data

  • Heads of government of the G7 countries. Retrieved 2026-09-27. View source
  • Everyone who has held the office that leads each G7 government: President of the United States, Prime Minister of the United Kingdom, Canada, Italy and Japan, President of France and Chancellor of Germany. Office records as held in Wikidata; people who held an office twice are counted once.
  • Verification: 256 of 263 included. A leader is included when Wikidata records one birth date at day precision. U.S. presidents must also match the official White House biography.
  • Expected values: every day of the years each group was born in, weighted by how many people were born in each year, run through CUE’s engine. Weighting matters for Chinese signs and Life Paths, which depend on the year.
  • A difference is called clear only in groups of 50 or more and at least three standard errors from expected. Because each study tests about a hundred values, a clear difference needs 3.5 standard errors; 2.5 to 3.5 is only “worth watching”.
Left out: 7 people whose exact birth date could not be confirmed
  • #3 Henry Pelham: Sources give more than one date
  • #12 William Petty, 2nd Earl of Shelburne: Sources give more than one date
  • #53 Adolphe Thiers: Sources give more than one date
  • #54 Patrice de MacMahon: Sources give more than one date
  • #69 John Sparrow David Thompson: Sources give more than one date
  • #145 Amintore Fanfani: Sources give more than one date
  • #258 Keir Starmer: Sources give more than one date
