Dates & Time

Three types

• date — year/month/day
• time — hour/min/sec
• datetime — both

Arithmetic with timedelta

datetime + timedelta(days=N, hours=H) works as you'd expect.

strftime / strptime

• dt.strftime("%Y-%m-%d") — format a datetime → string
• datetime.strptime(s, "%Y-%m-%d") — parse a string → datetime

Format codes: %Y year · %m month · %d day · %H:%M:%S time.

Try it

1. How many days until your next birthday?
2. Parse "28/06/2026" (DD/MM/YYYY).
