Each man must count seven weeks from the day the new wheat offering was brought after Passover

'You shall also count for yourselves from the day after the sabbath, from the day when you brought in the sheaf of the wave offering; there shall be seven complete sabbaths.

Hebrew

טו וּסְפַרְתֶּם לָכֶם, מִמָּחֳרַת הַשַּׁבָּת, מִיּוֹם הֲבִיאֲכֶם, אֶת-עֹמֶר הַתְּנוּפָה: שֶׁבַע שַׁבָּתוֹת, תְּמִימֹת תִּהְיֶינָה.
