I need my XTZ balance for a specific date in past. I am not sure how to get this as most blockexplorers do not offer a date field for searching historical balances. Can somebody help me?
You can get historical balance (at the specified datetime or block level) via TzKT API.
The baking bad block explorer lets you filter by date, by clicking the calendar icon: https://tzkt.io/
Paste the address you are interested in, into the search bar, then filter by date
