Greetings.
The current situation involves a significant number of domains within the .COM zone, with a primary base starting at 600+ and constantly changing with most cases leading to an increase. The task at hand is to accurately determine the date of the domain's expiration, as well as its release time without necessarily needing the former.

Regarding the question about what tools are best to use, my experience has shown that programs such as Whic are only available for a fee, which I am unwilling to pay. On the other hand, Netpeak Checker displays errors by showing active domains as already free. Both programs provide excellent results and allow for the outcome of the check to be compiled in a list. Could you kindly recommend these programs along with links? Thank you in advance for your attention, valued members of this forum.

I recommend testing out this service: http://www.seomastering.com/audit/seomastering.com/. It displays both the start and end dates of the domains you are interested in. If the domains have already expired, attempting a dropped parsing may be useful.

Additionally, you could also check out these domain search services:
