+# Leetcode: Problem-3280
+
+## Description:
+
+You are given a string ``date`` representing a Gregorian calendar date in the ``yyyy-mm-dd`` format. 
+``date`` can be written in its binary representation obtained by converting year, month, and day to their binary representations without any leading zeroes and writing them down in ``year-month-day`` format.
+Return the binary representation of ``date``.
+
+**Example 1:**
+Input: date = "2080-02-29"
+Output: "100000100000-10-11101"
+
+**Explanation:**
+100000100000, 10, and 11101 are the binary representations of 2080, 02, and 29 respectively.
+
+**Example 2:**
+Input: date = "1900-01-01"
+Output: "11101101100-1-1"
+
+**Explanation:**
+11101101100, 1, and 1 are the binary representations of 1900, 1, and 1 respectively.
+
+## Steps:
+**1. Date Input:** Given a date in the format YYYY-MM-DD.
+
+**2. Binary Conversion:**
+
+    • Convert the year (YYYY) to binary.
+    • Convert the month (MM) to binary.
+    • Convert the day (DD) to binary.
+
+**3. Output:** Provide the combined binary representation.
+
+# Solution in Java
+
+```java
+class Solution {
+    public String convertDateToBinary(String date) {
+        String[] parts = date.split("-");
+        int year = Integer.parseInt(parts[0]);
+        int month = Integer.parseInt(parts[1]);
+        int day = Integer.parseInt(parts[2]);
+
+        String yearBinary = Integer.toBinaryString(year);
+        String monthBinary = Integer.toBinaryString(month);
+        String dayBinary = Integer.toBinaryString(day);
+        return yearBinary + "-" + monthBinary + "-" + dayBinary;
+    }
+}
+```
