align all these series by date using VBA

From the original dataset, there are different series with different start date ie: some start with 2003 and some start from 2005 etc ….
Anyone know how can I align all these series by date by VBA instead of doing that manually for each series ?
align by date.xlsx

See if the attached works for you

Thank Jindon. This code is amazing !!! I tried to modify it to include the date for the series that has date starts later.
Do you know how can I do it ?

I don't understand what you are trying to say.
