Let's jump to it. To fetch records from today and onward in MySQL:

-- I see today and future, kinda like a fortune teller, eh?
SELECT * FROM your_cool_table WHERE pivotal_datetime >= CURDATE();

KEY NOTES:

CURDATE() scoops up the current date (time is on vacation).
>= sifts through for dates that are today and future dates.
Slot it into WHERE to achieve your desired results.

In case you need actual current time to be part of your destiny prediction:

-- Now I got the time too, feeling like Doctor Strange!
SELECT * FROM your_cool_table WHERE pivotal_datetime >= NOW();

How to tackle different time frames

Covering the basics: yesterday, today, and tomorrow

MySQL has a few tricks for filtering dates:

Yesterday's news: pivotal_datetime < CURDATE()
Presently on point: pivotal_datetime >= CURDATE() AND pivotal_datetime < DATE_ADD(CURDATE(), INTERVAL 1 DAY)
Tomorrow's world: pivotal_datetime >= DATE_ADD(CURDATE(), INTERVAL 1 DAY)

Nailing the in-betweeners

Want a range from today to a certain date? Here you go:

-- Hope you checked your future date in a crystal ball, didn't you?
SELECT * FROM your_cool_table WHERE pivotal_datetime BETWEEN CURDATE() AND '2024-12-12 23:59:59';

Remember: Time isn't considered here, use DATE_ADD instead if precision is necessary.

Time zones bandwagon

If snowflakes from different time zones apply:

-- Nobody is forgotten, we have a time zone redeemer here!
SELECT * FROM your_cool_table WHERE CONVERT_TZ(pivotal_datetime,'UTC','America/New_York') >= CURDATE();

Hitting the sweet spot when comparing date and datetime

When playing with date and datetime comparisons in MySQL, understand these variables:

Using CURDATE() might feel like cheating when you don't want to miss today's ongoing events.
Picking NOW() ensures you're on board with every event for the day.

Accuracy matters

Stay accurate when you only care for a date without its time:

-- Because who needs time when you have a date, right?
SELECT * FROM your_cool_table WHERE DATE(pivotal_datetime) = DATE(NOW());

Friendly advice for developers: Stay consistent in datetime field definitions and keep your server's time zone settings in check. Mind your gaps!
