"Make it clear from scripture based on the bible, where did a prophet or Jesus or his disciples/apostles tell us how to keep this feast we call Easter IN THE BIBLE?"
TL;DR: That's not possible. The Bible doesn't promote Easter, it condemns it.
Passover, and the following Days of Unleavened Bread, is a biblical festival celebrating the ancient Israelites' exodus from Egypt.
In early Chritianity, the festival was celebrated by the Apostles and new Christians with a fuller understanding of its prophetic significance. As Paul said in 1Corinthians 5:7-8,
Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificedIt for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
The Days of Unleavened Bread represent the repentance of a Christian, when they turn from sin and remove it from their lives.
Similarly Passover itself, symbolizes Jesus's sacrifice, he being killed at 3 in the afternoon on the Day of Preparation, at the same time as the lambs were sacrificed for the Passover seder.
Easter is an ancient, pre-Christian festival. The name comes from European mythology according to the Encyclopedia Britanica:
The name Easter, like the names of the days of the week, is a survival from the old Teutonic mythology. According to Bede [an eighth century monk] it is derived from Oestre, or Ostdra, the Anglo-Saxon goddess of spring, to whom the month answering to our April, and called Eoster-monath, was dedicated.
But the myth is ancient, originating with the myth of Semiramus and Nimrod: who had names such as Ishtar and Tammuz in Babylon; Isis and Osiris in Egypt; Astarte and Bel in Syria; Aphrodite, Cybele, or Venus, and Attis or Adonis in Greece and Rome.
Hot-cross buns too have pagan origins according to the Britanica article "bun":
It is quite probable that it has a far older and morIte interesting origin, as is suggested by an inquiry into the origin of hot cross buns. These cakes, which are now solely associated with the Christian Good Friday, are traceable to the remotest period of pagan history. Cakes were offered by ancient Egyptians to their moon goddess; and these had imprinted on them a pair of horns, symbolic of the ox at the sacrifice of which they were offered on the altar, or of the horned moon goddess, the equivalent of Ishtar of the Assyro-Babylonians. The Greeks offered such sacred cakes to Astarte and other divinities. This cake they called bous (ox), in allusion to the ox-symbol marked on it, and from the accusative boun it is suggested that the word 'bun' is derived. Like the Greeks, the Romans eat cross-bread at public sacrifices, such bread being usually purchased at the doors of the temple and taken in with them, a custom alluded to by St. Paul in I Cor. x.28. At Herculaneum two small loaves about 5 in. in diameter, and plainly marked with a cross, were found. In the Old Testament are references made in Jer. vii.18-xliv.19, to such sacred bread being offered to the moon goddess. The cross-bread was eaten by the pagan Saxons in honor of Eoster, their goddess of light. The Mexicans and Peruvians are shown to have had a similar custom. The custom, in fact, was practically universal, ...
We can see references (negative) to this tradition in Jeremiah 7:18:
The children gather wood, and the fathers kindle the fire, and the women knead their dough, to make cakes to the queen of heaven ...
Similarly, both Lent and sunrise services were condemned in Ezekiel 8:14:
Then he brought me to the door of the gate of the LORD's house which was toward the north; and, behold, there sat women weeping for Tammuz.
And he brought me into the inner court of the LORD's house, and, behold, at the door of the temple of the LORD, between the porch and the altar, were about five and twenty men, with their backs toward the temple of the LORD, and their faces toward the east; and they worshipped the sun toward the east.
Apostolic Christianity continued celebrating Passover for several centuries.
The eastern churches in Jerusalem and Asia Minor held to the Passover tradition.
Polycarp, a disciple of John, opposed Rome's position:
Neither could Anicetus persuade Polycarp not to observe what he had always observed with John the disciple of our Lord, and the other apostles with whom he had associated; neither could Polycarp persuade Anicetus to observe it, as he said that he ought to follow the customs of the presbyters that had preceded him.
Polycrates, a disciple and successor of Polycarp, also followed the original faith and wrote:
We ... keep the day scrupulously, without addition or subtraction. All of these [John, Philip, et al.] kept the 14th day of the month ... in accordance with the gospel, not deviating in the least but following the rule of faith. ... I ... am not afraid of threats. Better people than I have said: We must obey God rather than men...
Eventually, Constantine stepped in and Easter was enforced as the official celebration. Those that clung to the biblical holiday were condemned as heretics and Judaizers.
For many centuries after, any individuals or groups noticing that Easter was pagan while Passover was more naturally Christian, were "corrected" by the Roman church. Groups such as the Paulicians, Bogomils, Waldensians, and Cathars were slaughtered by the thousands.
