Where to see all the lock-in expiry dates?

Most of the stocks have various lock-in end dates with 1 Month, 3 Month, 6 Months, 1 Year and 3 Year etc (sometimes 1.5 to 2 year). It would be difficult to keep track of these for multiple stocks, is there any place
or tool where we can see all the lock-in end dates for various stocks? Also, who’d be selling and what percentage. Most often I have only seen it on various news channels and their websites. Would be really helpful if there’s some place or tool to track this or an easier way to know about it.

Thanks in advance.
