'One year old' in the Bible

Then to the sons of Israel you shall speak, saying, ‘Take a male goat for a sin offering, and a calf and a lamb, both one year old, without defect, for a burnt offering,

‘When the days of her purification are completed, for a son or for a daughter, she shall bring to the priest at the doorway of the tent of meeting a one year old lamb for a burnt offering and a young pigeon or a turtledove for a sin offering.

Now on the day when you wave the sheaf, you shall offer a male lamb one year old without defect for a burnt offering to the Lord.

Along with the bread you shall present seven one year old male lambs without defect, and a bull of the herd and two rams; they are to be a burnt offering to the Lord, with their grain offering and their drink offerings, an offering by fire of a soothing aroma to the Lord.

You shall also offer one male goat for a sin offering and two male lambs one year old for a sacrifice of peace offerings.
