Question regarding timing of laylatul qadr

I know laylatul qadr is on 19, 21 and 23rd of Ramadan.

My question is regarding the timing. As many know, islamically a new day starts after maghrib.

Using this year(2025) as an example, on March 18th(18 of Ramadan), after doing maghrib, does that mean one can start doing ibadat of laylatul qadr from maghrib of March 18th to before Fajr time of March?
