If you got accepted on 01/28/19 and I have the Path act thing up and have an est. date of 02/18/19 and on irs website will I still get my refund before the 27th of Feb.?

It depends.  You'll need to follow Where's My Refund on the IRS website.  They won't post information until February 15, because PATH Act does not allow them to issue refunds with the EITC CTC or AOC before then.

I was accepted on 1 24 19 WMR update today
It says still processing and we will provide you with a DDD when available as per last year I had a DDD the next day and yes they will not issue any refund until on or after 2 15 19

The Path message should lift this Friday and hopefully you'll have a ddd on this Saturday on WMR.

If you have access to your tax transcriptions you can possibly look at your transcipts this Friday and see the updated info a day early.

Hope this helps.

If next Monday is my 21 days can they still hold the refund because that’s a holiday?

21 days is how long you should wait to call and check status . It’s not necessarily the date it should be released . I wouldn’t expect a deposit on a fed Holiday tho.
