Discord Message ID Decoder - Instant Message Timestamp Extractor

Last updated March 22, 2026

Discord Message IDs

Every Discord message has a unique Snowflake ID that encodes the exact millisecond it was sent. This is useful for archiving conversations, finding messages from a specific time period, and using Discord's API to fetch messages around a specific timestamp. The Discord API accepts Snowflake IDs in the before, after, and around parameters of the message fetch endpoint.

Finding Messages by Date

const DISCORD_EPOCH = 1420070400000n;

// Convert a date to a Discord Snowflake ID
// Useful for fetching messages before/after a specific time
function dateToSnowflake(date) {
  const ms = BigInt(date.getTime()) - DISCORD_EPOCH;
  return String(ms << 22n);
}

// Decode a message ID to get its timestamp
function decodeMessageId(messageId) {
  const id = BigInt(messageId);
  const ms = Number((id >> 22n) + DISCORD_EPOCH);
  return {
    messageId,
    createdAt: new Date(ms).toISOString(),
    timestamp: ms
  };
}

// Fetch messages from a specific date using Discord API
async function fetchMessagesFromDate(channelId, date, token) {
  const snowflake = dateToSnowflake(date);
  const response = await fetch(
    `https://discord.com/api/v10/channels/${channelId}/messages?after=${snowflake}&limit=100`,
    { headers: { Authorization: `Bot ${token}` } }
  );
  return response.json();
}

Message ID Use Cases

• Archiving: Record message IDs to reconstruct conversation timelines.
• Moderation: Find messages sent during a specific incident window.
• Bots: Use after parameter to fetch only new messages since last check.
• Analytics: Count messages per time period by decoding ID timestamps.
