GENESIS 1:13
 

So the evening and the morning were the third day. [Genesis 1:13 NKJV]
 

There was evening, then morning—a third day. [Genesis 1:12 GW]

Bible Teacher:

What became the third day were not the things made or done on the third, but the evening and morning only were what became the third day. The day was counted by the third evening and the third morning, and not by the activities or lack of activities in them. And being the third day meant it was the third time or the third number of evening and morning since the beginning of God's creation of the Earth. However,
 

№* — There is difference between "What became the third day" and "What the third day became." Even as:
 

№* — There is difference between "What counts the Day (third day)" and "What the Day (third day) counts."
 

What became or counted the third day were the evening and morning at their third advent. But what the third day became or counted were things and events that came in and came by the third day.

Commentaries:

Same as the difference between "To number your days" and "To Weigh (account of) your days." Like Daniel pronounced the handwriting on the wall, "Mene, Mene (To number your days)" and then "Tekel (To Weigh your days)"
 

@ To Mene or To Number your days — is to truly estimate or count how many evenings and mornings are yet to become or count as days in your remaining lifetime.
 

@ To Tekel or To Weigh your days — is to truly review, compare or value the worth (evaluation) and significance of the things you did, things you said or things you made in your past days or past times already spent in your lifetime, on the scale of what was required of you and how much was required from you.

Bible Teacher:

The repeated events of evening and morning continued, and Time numbered that day "Third Day" or "Day Three." Evening and Morning were the only seasons that switched through in the third day like in the previous days, and no other seasons or weather conditions were setup in the third day. Yet, all those things that were accomplished in the third day alone were basically things that would require almost all the different seasons and weathers of a years before they are accomplished by natural standards. The Word and the Zeal of God are better time conditioners for accomplishing things through the earth or ground, more than the observable seasons and weather conditions of any part of the earth in any time or season.
 

• No Winter mentioned, no cold weather breeze noticed or no wind season captured; yet the waters were gathered together into one seas on the third day.
   
• No Summer mentioned, no Hot weather breeze noticed or no wind season captured; yet the dryland appeared out of wetness flood or a dryland was formed on the third day.
   
• No Springtime season mentioned, yet the plants grew up out of the earth's ground on the third day.
   
• No Autumn time season mentioned, yet the plants matured and bore fruits out of the earth's ground on the third day.
   

God changes times and seasons for His Word and Will, and not the other way around. Work and Watch through observing the Word and Will of God, than you do through observing the conditions of weathers and seasons. Instead of looking at climate change, rather be looking at the Words of God spoken in the season and out of season.
