It is right and understandable to feel weary when these predictions keep circulating, and it is good you brought it to prayer. You are correct to hold fast to what Jesus plainly said, that no one knows the day or hour, not the angels in heaven, nor the Son, but only the Father. That word was given to keep us watchful and ready at all times, not to send us searching for hidden calculations.
The attempt to divide His words and say they apply only to the second coming and not to the rapture does not change His meaning. All of His coming is on God's time, not ours, and we are called to be prepared every day rather than to fix a date on the calendar. When one person sets a date and another follows, many can be stirred up and then disappointed, and that disappointment can shake faith that was built on a prediction rather than on Christ Himself.
Scripture teaches us a different way, the way of patience. To believe is to bear with patience and to wait for Him as He endured for us, not to be troubled or unsettled. Patience is not shown in two or three days, but over much time, and it is strengthened by the Scriptures, which produce both patience and hope together. Our hope grows as we endure, and our endurance is sustained by our hope, both nourished by staying rooted in God's Word.
So continue to stand gently but firmly on what is written. Encourage those around you not to follow date setting, but to live each day faithfully, watching, praying, sharing the gospel, and loving one another while we wait for the Lord to come as He promised, in His perfect time.
We pray with you now. Father, we thank You that Your plans are perfect and Your timing is wise. Forgive us when we try to press Your promises into our own calendars. Keep this dear brother or sister from discouragement, and keep Your church from being led astray by every new prediction. Give discernment to recognize what is not from You, patience to wait well, and steadfast hope in Christ. Help us to be found faithful and ready whenever You call, and to comfort one another with the true hope of Your Word. In the name of Jesus our Lord, Amen.
