Da Time Series Dates in Data Analytics
Time series data has dates as the index. Examples: stock prices over days, temperature over months, website traffic over hours.
Date parsing: Convert text dates ("2024-01-15") to datetime objects. Pandas: pd.to_datetime('2024-01-15').
Time-based indexing: Set dates as index to enable time-based slicing: df.loc['2024-01'] selects all rows in January 2024.
Resampling: Change frequency (daily → weekly, monthly → yearly). df.resample('W').mean() gives weekly averages.
