I asked GROK about counting $ufd posts on 27th. So being EST i get to start my bullposting at 7pm tonight.

If you wanted to track how many posts were made with $UFD on January 27, 2024, you would start counting posts at 00:00 UTC on January 27, 2024, and continue until 23:59:59 UTC on the same day. This ensures that you capture all posts within that specific calendar day according to Coordinated Universal Time, which is the standard time reference for X's timestamping. 

Remember, if you are in a different time zone, you would need to convert UTC to your local time. For example, if you're in the Pacific Time Zone (PT), which is typically UTC-8, you would start counting at 4:00 PM PT on January 26, 2024, and end at 3:59:59 PM PT on January 27, 2024. However, always account for daylight saving time adjustments if applicable in your region.
