The Second Passover is observed on the 14th day of the second month, known as Iyar or Ziv. This month is significant because it is the designated time for the Second Passover, which is to be kept at twilight on the 14th day, just as the first Passover is observed in the first month. The only difference between the first and the Second Passover is the month in which it is observed. All rites and rituals of the Passover, including eating unleavened bread and bitter herbs, leaving none of it until morning, and not breaking any of its bones, are to be followed during the Second Passover.

Ziv, also known as Iyar, is the second month in the biblical calendar, and it holds significant events that reflect God's precise timing and providence. In Joshua 5:11-12, the "very same day" or "bone day" marks the moment when the Israelites ate the produce of the land, and the manna ceased after 40 years of divine provision. This day in the second month serves as an enduring memorial of God's faithfulness, looking back to the day when He first announced the manna on the 15th day of the second month, as recorded in Exodus 16:1. Furthermore, the events of Joshua 5 are understood to occur in the second month, aligning with the second Passover as described in Numbers 9:9-13, rather than the first month's Passover, due to the timing of the manna's cessation and the logistical challenges following the national circumcision. This reinforces the significance of Ziv/Iyar as a time when God's providence and the transition to new provisions are evident in the history of His people.

The events in Joshua 5, often linked to the timing of the Wavesheaf offering and the count to Pentecost, point to a significant moment in the second month, Ziv or Iyar. The cessation of manna, which had sustained the Israelites for forty years, occurred on the sixteenth day of this month, marking a transition to eating the produce of the land. This timing aligns with the second Passover, as outlined in Numbers 9:11, rather than the typical first-month Passover. The mention of unleavened bread in Joshua 5:11 does not necessarily indicate the Feast of Unleavened Bread, as it can also signify bread prepared in haste, a vital component of the second Passover. Furthermore, historical precedent under Hezekiah shows Unleavened Bread being observed in the second month after the second Passover. The circumcision of the Israelite men, occurring around the tenth or eleventh day of the first month, likely required significant recovery time, making it probable that many were not ceremonially clean for the first-month Passover due to potential infections or seepage from wounds. This supports the likelihood of observing the second Passover in Ziv or Iyar, adding to the reasons why the Wavesheaf offering is not recorded in Joshua 5.
