const todayYear = new Date().getFullYear()
mainLoop: for (let year = todayYear; year > todayYear - 100; year--) {
    for (let month = 1; month <= 12; month++) {
        for (let day = 1; day <= 31; day++) {
            const passphrase = `${year.toString().slice(-2)}${month.toString().padStart(2, '0')}${day.toString().padStart(2, '0')}`
            try {
                const isDecryptionSuccessful = decryptAndReplaceHtml(passphrase)
                if (!isDecryptionSuccessful) throw new Error('Decryption failed')
                console.log(`SUCC ${passphrase}`)
                break mainLoop
            } catch {
                console.log(`FAIL ${passphrase}`)
            }
        }
    }
}

Haha funny and intriguing code... TOSS friends would like it
