I am a dedicated viewer of the beloved Japanese anime, Doraemon. The series is close to my heart, with characters each having a unique personality. However, I have noticed a gap with Shizuka and Suneo's birthdays and age placement, causing an inconsistency issue with the narrative.

Shizuka's birthday is set in May and Suneo's in February. Suneo is said to be the youngest of the four, allegedly born a year later than the other three and Shizuka is said to be the oldest. However, a plot inconsistency exists in 1979 Doraemon anime episode where Suneo and Gian are seen as babies at the same time, implying they belong to the same age group. On further deliberation, if Suneo was born in February the same year as Gian, Nobita, and Shizuka, he would technically not be in the same grade as them due to Japan's school year starting in April. 

This may seem inconsequential, but to followers of the series, the continuity is important for enjoying the timeless charm of the show. It may influence how we perceive the character dynamics. Hence, to set things right, I propose that Fujiko F. Fujio Pro and TV Asahi should revise Shizuka's and Suneo's birthdays that is to change Shizuka's birthday to October 10 and Suneo's birthday to May 29 and also Dekisugi's birthday to June 11 and Jaiko's birthday to July 19 to make more sense and avoid confusement and align with the 1979 Doraemon anime episode where Suneo and Gian were shown as babies on the day Nobita was born, so this will make Suneo the rightful oldest of the four and the oldest among his friends and classmates at the exact most and if Suneo was born on May 29, he would be almost a month older than Gian who was born on June 15, almost 3 months older than Nobita who was born on August 7, and almost 5 months older than Shizuka who was born on October 10, based on how the Japanese school system works, the Japanese school year starts in April and the Japanese educational system is that children born between April 2 to April 1 of the following year would typically be in the same grade, so this will make Suneo to be assumed as the rightful oldest of the four and the oldest among his friends and classmates at most.

I ask all Doraemon fans and supporters of continuous and accurate storytelling to stand with me on this. Let's urge Fujiko F. Fujio Pro to fix this inconsistency for the sake of an airtight and logical narrative. Please sign this petition and join me in my endeavor.
