Across the 23 complete years 2000–2022, the busiest birthday in Malaysia is October 10, at 111.8 on an index where the average day is 100. The three busiest dates are October 10, November 11, September 9: 10/10, 11/11 and 9/9. The quietest is December 25 at 88.0.

What this series is

Malaysia's National Registration Department records live births by date of birth, and the Department of Statistics publishes the daily series openly on data.gov.my under CC BY 4.0. The download covers the whole country as a single series.

The file downloaded on September 15, 2026 holds 37,833 daily rows from 1920-01-01 to 2023-07-31, totalling 35,959,623 births. Before anything was computed, every row was checked: one row per calendar date, every day of every year present, every count a whole number of zero or more, and February 29 present in every leap year. The final year, 2023, stops part-way (212 days, 267,246 births) and is excluded from every ranking on this page, because a part-year would give some months more observed days than others.

Ranks here use the 23 complete years 2000–2022: 8,401 days and 11,760,772 births, measured per occurrence, so leap day is judged on the years it occurred. The series reaches back to 1920, but the early decades were registered under very different administrative conditions, so the ranking starts at 2000.

An exploratory look at the twelve repeated-digit dates

Malaysia’s three busiest dates are all dates where the day number matches the month number. That invites a look at the whole set of twelve such dates: January 1, February 2, March 3, April 4, May 5, June 6, July 7, August 8, September 9, October 10, November 11 and December 12. This is an exploratory comparison, chosen after seeing the top of the ranking, and twelve dates are few.

To keep the two countries comparable, both columns below use the same matched window 2007–2014 and the same per-occurrence index. Across the twelve dates the Malaysian index averages 104.7 against 99.3 in the United States. The average hides variation: 9 of the twelve are above 100 in Malaysia and 3 at or below it, so read the date-by-date column.

The main Malaysian ranking above uses the 23 complete modern years 2000–2022; only this comparison narrows to the matched window, because it puts two countries side by side. This is an observed calendar pattern; the file holds daily totals.

The Malaysian year by month

September is the busiest month at 106.2 and January the quietest at 95.4. December 25 and January 1 are below average here too, though less sharply than in the European series. Malaysia’s public holidays mix fixed dates with dates set by the lunar and Islamic calendars, so only some of them fall on the same calendar date each year. Holiday tests on this site cover the United States and England and Wales.

Malaysia in the matched comparison

Malaysia covers 2007–2014 completely, so it is one of the five series in the matched cross-country study: 4,197,822 births over 2,922 days in that window. The five series are ranked separately.

The publisher’s caveats

• Counts come from registrations with the National Registration Department, so under-registration is possible, particularly in earlier decades and in remote areas.
• The publisher revises historical figures; this page reflects the file as downloaded on September 15, 2026, whose server copy was last modified September 14, 2023.
• The catalogue page describes the series as running to the present, but the actual file ends 2023-07-31. The downloaded coverage is what is used here.
• Malaysian rankings answer a Malaysian question. The rarity result on the homepage is United States only.
