Explaining time differences

I could offer to generate a conversion table for specific dates or provide a brief overview of date conversion. Regarding Eastern Time, it includes both EST and EDT. For example, in December (EST) the difference is 13 hours, and in June (EDT) it's 12 hours. Beijing time is ET + 12 or +13, depending on the daylight saving time. I could also mention the 2022 Qatar schedule used local time, while the upcoming 2026 tournaments use local time across the US, Mexico, and Canada. I think including methods for identifying daylight saving time and providing a short formula for conversions could be useful too. I'd also ask if the user wants me to convert a list.Creating concise bullets

I’m putting together some concise bullet points in Chinese about time differences:

• Eastern Time has daylight saving (EDT UTC-4) and standard time (EST UTC-5).
• Beijing Time is UTC+8.
• So, the difference is BJT – ET = 12 hours (during EDT) or 13 hours (during EST).
• Daylight saving time runs from the second Sunday in March to the first Sunday in November.
• Quick formula: Beijing Time = Eastern Time + 12h/13h depending on daylight saving.
• Example: 2025-07-01 20:00 ET → Beijing 2025-07-02 08:00; 2025-12-01 20:00 ET → Beijing 2025-12-02 09:00.

I might also ask if the user needs me to convert any schedule to Beijing Time. It’s important to remind them that my earlier claim about a "12-hour difference" isn’t always accurate!
