Sir, there are a few Case Laws (Income Tax Appellate Tribunal Decisions) which have held that the time limit of 6 months is actually 6 calendar months and not 180 days. So, the time limit of 6 months is reckoned to be the end of the month in which the period of 6 months expires. In your case it will end of Feb 2020 i.e 29-Feb-2020.
I have given summary of one such case law for your Reference. In this case, Shares were sold as per Assesse on 28-Feb-2005 but department contended that the shares were sold as on date of Board Resolution 24-Feb-2005. In either case, the date of investment being 30-Aug-2005, was allowed to be within the period of 6 months.

IN THE ITAT MUMBAI BENCH 'G'
Yahya E. Dhariwala v. Deputy Commissioner of Income-tax, Circle-15(2)
IT: For purpose of section 54EC, period of six months has to be reckoned from end of month in which transfer took place
Below is the extract of Para 14 of the Order:
14. In view of the above discussion and from the language in section 54EC, we are of the opinion that six months period should be reckoned from the end of the month in which the transfer takes place. As the investment has been made on 30th August 2005, we hold that the assessee has invested a part of the capital gain within a period of six months after the date of transfer of the long term asset in question in specified assets. We order accordingly. The grounds raised by the assessee are allowed.
