URGENT - Early arvit for Yom Tov on mosae Shabat

Dear rabbis,

For the sake of shalom bayit, may one pray arvit of Yom Tov (Pesah) early while it is still Shabbat? If so, what is the earliest? Plag? I realize that Shema would have to be said after seder. Correct? My wife is very strict with schedules and I want to avoid any issues that may arise due to starting everything later.

Thank you.

The best would be to wait until shkia to pray. You may begin the seder 25 minutes after shkia. That should be somewhere around 7:40.

7:40 in Lakewood?

Lakewood, Brooklyn
Should be around then.

It should be noted that one may not start preparing until Shabbat is over.
