TL;DR: You can simply enables search functionality in Qwen Chat to ensure accuracy in Gregorian-Chinese calendar conversions.

Specifically, the calculation of the Chinese Calendar involves complex astronomical models and human-defined rules. As a result, converting dates between the Gregorian and Chinese Calendars cannot be easily expressed in analytical form, making it extremely difficult for models to compute accurately. The most reliable method for converting between these calendars is to use the official almanac "Chinese Astronomical Almanac" 《中国天文年历》, published by the Purple Mountain Observatory, which provides pre-calculated and authoritative date correspondences. Since this information is purely based on memorization, models, like the general public, are prone to inaccuracies when relying solely on memorized data. To guarantee accuracy, looking up the information remains the only reliable approach.

I don't agree your option. DeepSeek/Doubao and so many other LLMs don't make mistake with the same problem.

They don't need use search functionality. They can give right answer by LLM themself.

I don't know what's problem about your Deepseek account. My Deepseek give right answer. []Deepseek(url)
