Relative times for days
In English, we have a few ways of referring to time, relative to the current time. Mandarin is similar, and has a few patterns.
For days:
天 (Tiān) is day (although it can relate to the heavens, God, and much more)
Although 每个天 (Měi gè tiān) is literally “every (or each) day”, doubling-up the character as 天天 (Tiāntiān) can also be used for every day
今天 (Jīntiān) is today
昨天 (Zuótiān) is yesterday
