Tomorrow will be the 7th Sabbath
Lev 23:15 And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:
The next day (a Genesis 1st Day) our modern Sunday
Lev 23:16 Even unto the morrow after the seventh Sabbath shall ye number fifty days; and ye shall offer a new meat offering unto YHWH.
Some may observe Shavuot the day after next Sabbath depending on various variant factors.
But it is certain we are to count 7 Sabbaths not 7 Tuesdays or 7 Thursdays, etc. – This is based on a fallacy that Abib 16 is even mentioned let alone commanded in Scripture.
